2014-10-21usb: gadget: function: uvc: conditionally dequeueFelipe Balbi1-1/+2
We shouldn't try to dequeue a NULL pointer. Signed-off-by: Felipe Balbi <balbi@ti.com>
2014-10-21usb: dwc3: gadget: fix set_halt() bug with pending transfersFelipe Balbi3-7/+15
According to our Gadget Framework API documentation, ->set_halt() *must* return -EAGAIN if we have pending transfers (on either direction) or FIFO isn't empty (on TX endpoints). Fix this bug so that the mass storage gadget can be used without stall=0 parameter. This patch should be backported to all kernels since v3.2.

2014-10-21usb: dwc3: gadget: hold the lock through set_wedge()'s lifeFelipe Balbi1-3/+6
Instead of releasing the lock and calling locked versions of our set_halt() methods, let's hold the lock all the way through and call unlocked versions of those functions. Signed-off-by: Felipe Balbi <balbi@ti.com>
2014-10-21usb: dwc3: gadget: move isoc endpoint check to unlocked set_haltFelipe Balbi1-8/+5
__dwc3_gadget_ep_set_halt() is the function which handles the actual halt feature. In order to cope with some extra cleanup comming as a follow-up patch let's move the isochronous endpoint check there too. Signed-off-by: Felipe Balbi <balbi@ti.com>
2014-10-21usb: dwc3: ep0: hold our lock in dwc3_gadget_ep0_set_haltFelipe Balbi2-1/+16
dwc3_gadget_ep0_set_halt() will be called without locks held in some cases, so we must hold the lock on our own. While at that, also add a version without locks to be called in certain conditions. Signed-off-by: Felipe Balbi <balbi@ti.com>
2014-10-21usb: dwc3: trace: don't dereference pointersFelipe Balbi1-15/+38
The way trace works is that it won't decode strings until we read the actual trace. Because of that, we can't make assumptions of pointers still being valid at the time we read the trace. In order to avoid that, just copy all fields from every struct pointer we need for our traces. Ths patch fixes the following bug: [ 2940.039229] Unable to handle kernel paging request at virtual address 814efa9e [ 2940.046904] pgd = ec3dc000 [ 2940.049737] [814efa9e] *pgd=00000000 [ 2940.053552] Internal error: Oops: 5 [#1] SMP ARM [ 2940.058379] Modules linked in: usb_f_acm u_serial g_serial usb_f_uac2 libcomposite configfs xhci_hcd dwc3 udc_core matrix_keypad dwc3_omap lis3lv02d_i2c lis3lv02d input_polldev [last unloaded: g_audio] [ 2940.077238] CPU: 0 PID: 3020 Comm: tail Tainted: G W 3.17.0-rc5-dirty #1097 [ 2940.085596] task: ed1b1040 ti: ed07c000 task.ti: ed07c000 [ 2940.091258] PC is at strnlen+0x18/0x68 [ 2940.095177] LR is at 0xfffffffe [ 2940.098454] pc : [<c0356df8>] lr : [<fffffffe>] psr: a0000013 [ 2940.098454] sp : ed07ddb0 ip : ed07ddc0 fp : ed07ddbc [ 2940.110445] r10: c070ff70 r9 : ed07de70 r8 : 00000000 [ 2940.115906] r7 : 814efa9e r6 : ffffffff r5 : ed4b6087 r4 : ed4b50c7 [ 2940.122726] r3 : 00000000 r2 : 814efa9e r1 : ffffffff r0 : 814efa9e [ 2940.129546] Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user [ 2940.137000] Control: 10c5387d Table: ac3dc059 DAC: 00000015 [ 2940.143006] Process tail (pid: 3020, stack limit = 0xed07c248) [ 2940.149098] Stack: (0xed07ddb0 to 0xed07e000) [ 2940.153660] dda0: ed07dde4 ed07ddc0 c0359628 c0356dec [ 2940.162203] ddc0: 00000000 ed4b50c7 bf03ae9c ed4b6087 bf03ae9e 00000002 ed07de3c ed07dde8 [ 2940.170740] dde0: c035ab50 c0359600 ffffffff ffffffff ff0a0000 ffffffff ed07de30 ed4b5088 [ 2940.179275] de00: ed4b50c7 00000fc0 ff0a0004 ffffffff ed4b5088 ed4b5088 00000000 00001000 [ 2940.187810] de20: 00001008 00000fc0 ed4b5088 00000000 ed07de68 ed07de40 c00f1e64 c035a9c4 [ 2940.196341] de40: bf03dae0 ed07de70 ed4b4000 ec25b280 ed4b4000 ec25b280 bf03dae0 ed07de9c [ 2940.204886] de60: ed07de78 bf033324 c00f1e0c bf03ae9c 814efa9e ed428bc0 814eca3e 00000000 [ 2940.213428] de80: 814eba3e ed4b4000 03bd1201 c0c34790 ed07ded4 ed07dea0 c00edc0c bf0332d0 [ 2940.221994] dea0: 000002c7 ed07df10 ed07decc ed07deb8 ed4b4000 0000209c ec278ac0 00000000 [ 2940.230536] dec0: 00002000 ec0db340 ed07def4 ed07ded8 c00ee7ec c00eda90 c00ee7b0 ec278ac0 [ 2940.239075] dee0: ed4b4000 000002d5 ed07df44 ed07def8 c018b8d0 c00ee7bc c0166d3c ec278af0 [ 2940.247621] df00: 0001f090 ed07df78 000002c7 00000000 000002c8 00000000 00000000 ec0db340 [ 2940.256173] df20: 0001f090 ed07df78 ec0db340 00002000 0001f090 00000000 ed07df74 ed07df48 [ 2940.264729] df40: c0166e98 c018b5f4 00000001 c018535c 000168c1 00000000 ec0db340 ec0db340 [ 2940.273284] df60: 00002000 0001f090 ed07dfa4 ed07df78 c01675c4 c0166e0c 000168c1 00000000 [ 2940.281829] df80: 00002000 0000000a 0001f090 00000003 c000f064 ed07c000 00000000 ed07dfa8 [ 2940.290365] dfa0: c000ede0 c0167584 00002000 0000000a 00000003 0001f090 00002000 00000000 [ 2940.298909] dfc0: 00002000 0000000a 0001f090 00000003 7fffe000 0001e1e0 00002004 0000002f [ 2940.307445] dfe0: 00000000 beed38ec 000104c8 b6e6397c 40000010 00000003 00000000 00000000 [ 2940.315992] [<c0356df8>] (strnlen) from [<c0359628>] (string.isra.8+0x34/0xe8) [ 2940.323534] [<c0359628>] (string.isra.8) from [<c035ab50>] (vsnprintf+0x198/0x3fc) [ 2940.331461] [<c035ab50>] (vsnprintf) from [<c00f1e64>] (trace_seq_printf+0x68/0x94) [ 2940.339494] [<c00f1e64>] (trace_seq_printf) from [<bf033324>] (ftrace_raw_output_dwc3_log_request+0x60/0x78 [dwc3]) [ 2940.350424] [<bf033324>] (ftrace_raw_output_dwc3_log_request [dwc3]) from [<c00edc0c>] (print_trace_line+0x188/0x418) [ 2940.361507] [<c00edc0c>] (print_trace_line) from [<c00ee7ec>] (s_show+0x3c/0x12c) [ 2940.369330] [<c00ee7ec>] (s_show) from [<c018b8d0>] (seq_read+0x2e8/0x4a0) [ 2940.376519] [<c018b8d0>] (seq_read) from [<c0166e98>] (vfs_read+0x98/0x158) [ 2940.383796] [<c0166e98>] (vfs_read) from [<c01675c4>] (SyS_read+0x4c/0xa0) [ 2940.390981] [<c01675c4>] (SyS_read) from [<c000ede0>] (ret_fast_syscall+0x0/0x48) [ 2940.398792] Code: e24cb004 e3510000 e241e001 0a000011 (e5d01000) [ 2940.406980] ---[ end trace d8b38370fbb531f3 ]--- Signed-off-by: Felipe Balbi <balbi@ti.com>

2014-10-20watchdog: sunxi: Add A31 watchdog supportChen-Yu Tsai1-0/+10
This patch adds support for the watchdog hardware found in A31 and newer SoCs. This new hardware has registers at different offsets, and the system reset control has been split out of the "mode" register into a new "configuration" register. Differences not supported by this driver include separate interrupt lines for each watchdog, instead of sharing an interrupt line and registers with the timer block.

2014-10-20ax88179_178a: fix bonding failureIan Morgan1-1/+6
The following patch fixes a bug which causes the ax88179_178a driver to be incapable of being added to a bond. When I brought up the issue with the bonding maintainers, they indicated that the real problem was with the NIC driver which must return zero for success (of setting the MAC address). I see that several other NIC drivers follow that pattern by either simply always returing zero, or by passing through a negative (error) result while rewriting any positive return code to zero. With that same philisophy applied to the ax88179_178a driver, it allows it to work correctly with the bonding driver. I believe this is suitable for queuing in -stable, as it's a small, simple, and obvious fix that corrects a defect with no other known workaround. This patch is against vanilla 3.17(.0).

2014-10-20staging: comedi: (regression) channel list must be set for COMEDI_CMD ioctlIan Abbott1-8/+7
`do_cmd_ioctl()`, the handler for the `COMEDI_CMD` ioctl can incorrectly call the Comedi subdevice's `do_cmd()` handler with a NULL channel list pointer. This is a regression as the `do_cmd()` handler has never been expected to deal with that, leading to a kernel OOPS when it tries to dereference it. A NULL channel list pointer is allowed for the `COMEDI_CMDTEST` ioctl, handled by `do_cmdtest_ioctl()` and the subdevice's `do_cmdtest()` handler, but not for the `COMEDI_CMD` ioctl and its handlers. Both `do_cmd_ioctl()` and `do_cmdtest_ioctl()` call `__comedi_get_user_chanlist()` to copy the channel list from user memory into dynamically allocated kernel memory and check it for consistency. That function currently returns 0 if the `user_chanlist` parameter (pointing to the channel list in user memory) is NULL. That's fine for `do_cmdtest_ioctl()`, but `do_cmd_ioctl()` incorrectly assumes the kernel copy of the channel list has been set-up correctly. Fix it by not allowing the `user_chanlist` parameter to be NULL in `__comedi_get_user_chanlist()`, and only calling it from `do_cmdtest_ioctl()` if the parameter is non-NULL. Thanks to Bernd Porr for reporting the bug via an initial patch sent privately.
