Code did not handle projected 2d and depth coordinates, meaning potentially set 3d or cube special handling might stick.

2010-06-30Staging: comedi: drivers: adl_pci9111: Fix AI commands in TRIG_FOLLOW caseIan Abbott1-3/+6
I received a report that AI streaming acquisitions do not work properly for the adl_pci9111 driver when convert_src is TRIG_TIMER and scan_begin_src is TRIG_FOLLOW (and scan_begin_arg is therefore 0). This seems to be down to the incorrect setting of dev_private->scan_delay in pci9111_ai_do_cmd(). Under the previously stated conditions, dev_private->scan_delay ends up set to (unsigned int)-1, but it ought to be set to 0. The function sets it to 0 initially, and it only makes sense to change it if both convert_src and scan_begin_src are set to TRIG_TIMER. Note: 'scan_delay' is the number of unwanted scans to discard after each valid scan. The hardware does not support 'scan' timing as such, just a regularly paced conversion timer (with automatic channel switching between conversions). The driver simulates a scan period that is some (>1) multiple of the conversion period times the scan length (chanlist_len samples) by reading chanlist_len samples and discarding the next scan_delay times chanlist_len samples.

2010-06-30USB: gadget: f_mass_storage: stale common->fsg value bug fixMichal Nazarewicz1-99/+61
On fsg_unbind the common->fsg pointer was not NULLed if the unbound fsg_dev instance was the current one. As an effect, the incorrect pointer was preserved in all further operations which caused do_set_interface to reference an invalid region. This commit fixes this by raising an exception in fsg_bind which will change the common->fsg pointer. This also requires an wait queue so that the thread in fsg_bind can wait till the worker thread handles the exception. This commit removes also a config and new_config fields of fsg_common as they are no longer needed since fsg can be used to determine whether function is active or not. Moreover, this commit removes possible race condition where the fsg field was modified in both the worker thread and form various other contexts. This is fixed by replacing prev_fsg with new_fsg. At this point, fsg is assigned only in worker thread.

The usb_ep_autoconfig was called in fsg_bind using the original descriptors. In effect copied descriptors were not updated. This patch changes the copy full speed descriptors after the call to usb_op_autoconfig is performed. This way, copied full speed descriptors have updated values.

2010-06-30USB: musb: Enable the maximum supported burst mode for DMAHema HK1-11/+2
Setting MUSB Burst Mode 3 automatically enables support for lower burst modes (BURST4, BURST8, BURST16 or bursts of unspecified length). There is no need to set these burst modes based on the packet size. Also enable the burst mode for both mode1 and mode0. This is a fix for buggy hardware - having the lower burst modes enabled can potentially cause lockups of the DMA engine used in OMAP2/3/4 chips.

2010-06-30USB: obey the sysfs power/wakeup settingAlan Stern1-10/+3
This patch (as1403) is a partial reversion of an earlier change (commit 5f677f1d45b2bf08085bbba7394392dfa586fa8e "USB: fix remote wakeup settings during system sleep"). After hearing from a user, I realized that remote wakeup should be enabled during system sleep whenever userspace allows it, and not only if a driver requests it too. Indeed, there could be a device with no driver, that does nothing but generate a wakeup request when the user presses a button. Such a device should be allowed to do its job. The problem fixed by the earlier patch -- device generating a wakeup request for no reason, causing system suspend to abort -- was also addressed by a later patch ("USB: don't enable remote wakeup by default", accepted but not yet merged into mainline). The device won't be able to generate the bogus wakeup requests because it will be disabled for remote wakeup by default. Hence this reversion will not re-introduce any old problems.

2010-06-30usb: musb: Fix a bug by making suspend interrupt available in device modeMaulik Mankad1-1/+2
As a part of aligning the ISR code for MUSB with the specs, the ISR code was re-written. See Commit 1c25fda4a09e8229800979986ef399401053b46e (usb: musb: handle irqs in the order dictated by programming guide) With this the suspend interrupt came accidently under CONFIG_USB_MUSB_HDRC_HCD. The fix brings suspend interrupt handling outside CONFIG_USB_MUSB_HDRC_HCD.

2010-06-30USB: xHCI: Fix bug in link TRB activation change.Sarah Sharp1-16/+46
Commit 6c12db90f19727c76990e7f4801c67a148b30111 introduced a bug for control transfers. The patch was supposed to change when the link TRBs at the end of each ring segment were given to the hardware. If a transfer descriptor (TD) ended just before the link TRB, the code wouldn't give back the link TRB to the hardware; instead it would be given back in prepare_ring() just before the next TD was enqueued at the top of the ring. Unfortunately, the code relied on checking the chain bit of the TRB to determine whether the TD ended just before the link TRB. It assumed that the ring enqueuing code would call prepare_ring() before enqueuing the next TD. However, control transfers are made of multiple TDs, and prepare_ring() is only called once before enqueuing two or three TDs. If the first or second TD of the control transfer ended just before the link TRB, then the code in inc_enq() would not move the enqueue pointer past the link TRB, and the link TRB would get overwritten. This would cause the xHCI driver to start writing to memory past the ring segment, and eventually the system would crash or hang. The fix is to add a flag to inc_enq() that says whether the caller will enqueue more TDs before calling prepare_ring(). If the chain bit is cleared (meaning this is the last TRB in a TD), and the caller will not enqueue more TDs, then we defer giving back the link TRB.

2010-06-30USB: gadget: g_fs: possible invalid pointer reference bug fixedMichal Nazarewicz1-0/+11
During __gfs_do_config() some invalid pointers may be left in usb_configuration::interfaces array from previous calls to the __gfs_do_config() for the same configuration. This will always happen if an user space function which has a fewer then the last user space function registers itself. Composite's set_config() function that a pointer after the last interface in usb_configuration::interface is NULL unless the array is full. This patch makes the __gfs_do_config() make sure that if the usb_configuration::interface is not full then a pointer after the last interface is NULL.
