2014-09-30arm, fbdev, omap2, LLVMLinux: Remove nested function from omapfbBehan Webster1-7/+7
Replace the use of nested functions where a normal function will suffice. Nested functions are not liked by upstream kernel developers in general. Their use breaks the use of clang as a compiler, and doesn't make the code any better. This code now works for both gcc and clang.

2014-09-09video: mx3fb: always enable BACKLIGHT_LCD_SUPPORTArnd Bergmann1-1/+2
Commit 7edaa761ee81b ("video: mx3fb: Add backlight control support") changed the mx3fb driver so it always selects the BACKLIGHT_CLASS_DEVICE symbol, but that is hidden behind BACKLIGHT_LCD_SUPPORT in Kconfig, so we get a Kconfig warning for multi_v5_defconfig, which doesn't have that: Warning: (DRM_RADEON && DRM_NOUVEAU && DRM_I915 && DRM_GMA500 && DRM_SHMOBILE && DRM_TILCDC && FB_BACKLIGHT && FB_MX3 && USB_APPLEDISPLAY && FB_OLPC_DCON && ASUS_LAPTOP && SONY_LAPTOP && THINKPAD_ACPI && EEEPC_LAPTOP && ACPI_CMPC && SAMSUNG_Q10) selects BACKLIGHT_CLASS_DEVICE which has unmet direct dependencies (HAS_IOMEM && BACKLIGHT_LCD_SUPPORT) This makes sure we always enable both symbols together for mx3fb, like we do for the other drivers that can't be built without backlight support. Note that a better solution would be to ensure the driver can work with or without backlight support.

2014-08-22net: fec: ptp: avoid register access when ipg clock is disabledNimrod Andy3-15/+41
The current kernel hang on i.MX6SX with rootfs mount from MMC. The root cause is that ptp uses a periodic timer to access enet register even if ipg clock is disabled. FEC ptp driver start one period timer to read 1588 counter register in the ptp init function that is called after FEC driver is probed. To save power, after FEC probe finish, FEC driver disable all clocks including ipg clock that is needed for register access. i.MX5x, i.MX6q/dl/sl FEC register access don't cause system hang when ipg clock is disabled, just return zero value. But for i.MX6sx SOC, it cause system hang. To avoid the issue, we need to check ptp clock status before ptp timer count access.

The next patch is contributed by Dan Carpenter, it fixes the error handling in the c_can's probe function. Then there are two patches for the flexcan driver, one by Alexander Stein, which fixes the resetting of the bus error interrupt mask, the other one by Sebastian Andrzej Siewior which adds an additional error state transition message. ==================== Signed-off-by: David S.

2014-08-22cxgb4: Fix race condition in cleanupAnish Bhatt2-14/+19
There is a possible race condition when we unregister the PCI Driver and then flush/destroy the global "workq". This could lead to situations where there are tasks on the Work Queue with references to now deleted adapter data structures. Instead, have per-adapter Work Queues which were instantiated and torn down in init_one() and remove_one(), respectively. v2: Remove unnecessary call to flush_workqueue() before destroy_workqueue() Signed-off-by: Anish Bhatt <anish@chelsio.com> Signed-off-by: Casey Leedom <leedom@chelsio.com> Acked-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

2014-08-22sh: intc: Confine SH_INTC to platforms that need itGeert Uytterhoeven2-3/+6
Currently the sh-intc driver is compiled on all SuperH and non-multiplatform SH-Mobile platforms, while it's only used on a limited number of platforms: - SuperH: SH2(A), SH3(A), SH4(A)(L) (all but SH5) - ARM: sh7372, sh73a0 Drop the "default y" on SH_INTC, make all CPU platforms that use it select it, and protect all sub-options by "if SH_INTC" to fix this.

2014-08-22bnx2x: Revert UNDI flushing mechanismYuval Mintz1-75/+17
Commit 91ebb929b6f8 ("bnx2x: Add support for Multi-Function UNDI") [which was later supposedly fixed by de682941eef3 ("bnx2x: Fix UNDI driver unload")] introduced a bug in which in some [yet-to-be-determined] scenarios the alternative flushing mechanism which was to guarantee the Rx buffers are empty before resetting them during device probe will fail. If this happens, when device will be loaded once more a fatal attention will occur; Since this most likely happens in boot from SAN scenarios, the machine will fail to load. Notice this may occur not only in the 'Multi-Function' scenario but in the regular scenario as well, i.e., this introduced a regression in the driver's ability to perform boot from SAN. The patch reverts the mechanism and applies the old scheme to multi-function devices as well as to single-function devices.

2014-08-22qlcnic: Fix endianess issue in firmware load from file operationShahed Shaikh1-10/+25
Firmware binary file is in little endian. On big-endian architecture, while writing this binary FW file to adapters memory, writel() swaps the data resulting into corruption of FW image. So, swap the data before writing into adapters memory. Signed-off-by: Shahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Firmware dump template header is read from adapter using readl() which swaps the data. So, adjust structure element on the boundary of 32bit dword.

2014-08-22qlcnic: Fix flash access interface to applicationJitendra Kalsaria3-5/+32
Application expects flash data in little endian, but driver reads/writes flash data using readl()/writel() APIs which swaps data on big endian machine. So, swap the data after reading from and before writing to flash memory.

2014-08-22macvlan: Allow setting multicast filter on all macvlan typesVlad Yasevich1-2/+8
Currently, macvlan code restricts multicast and unicast filter setting only to passthru devices. As a result, if a guest using macvtap wants to receive multicast traffic, it has to set IFF_ALLMULTI or IFF_PROMISC. This patch makes it possible to use the fdb interface to add multicast addresses to the filter thus allowing a guest to receive only targeted multicast traffic.
