As reported by Stephen: After merging the v4l-dvb tree, today's linux-next build (x86_64 allmodconfig) failed like this: ERROR: "sms_ir_exit" [drivers/media/common/siano/smsmdtv.ko] undefined! ERROR: "sms_ir_event" [drivers/media/common/siano/smsmdtv.ko] undefined! ERROR: "sms_ir_init" [drivers/media/common/siano/smsmdtv.ko] undefined! The smsir file should be part of the smsmdtv core, if RC is defined. Fix it. Reported-by:Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by:

Since b9bf2eaf, the function ds3000_firmware_ondemand() is called only once during init. This locking scheme may have been useful when the firmware was loaded at each tune. Furthermore, it looks like this 'lock' was put in to prevent concurrent access (and not recursion as the comments suggest). However, this open- coded mechanism is anything but race-free and should have used a proper mutex. Signed-off-by:

The function cx25821_sram_channel_setup_upstream_audio always return zero, so the return value is not saved any more. Convert a nonnegative error return code to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by:

The dma_queue list is accessed by both the interrupt handler and by normal code. It needs to be protected by a lock to prevent possible list corruption. Corruption has been observed in 'real-life' conditions. Adding this lock made it go away. Signed-off-by:

v4l2_subdev_link_validate_get_format() retrieves the remote pad format depending on the entity type and prints a warning if the entity type is not supported. The type check doesn't take the subtype into account, and thus always prints a warning for device node types, even when supported. Fix it. Signed-off-by:

Set "y_skip_top" to zero and revise comment as I do not see this line corruption on two different mt9v022 setups. The first read-out line is perfectly fine.

Some camera systems cannot operate mt9v022 in normal mode and use only the snapshot mode. The TechNote for mt9v022 (TN0960) and mt9v024 (TN-09-225) describes required register settings when configuring the snapshot operation. The snapshot mode requires that certain automatic functions of the image sensor should be disabled or set to fixed values. According to the TechNote bit 2 and bit 9 in the register 0x20 must be set in snapshot mode and unset for normal operation. This applies for mt9v022 Rev.3 and mt9v024. Add required reg. 0x20 settings dependent on sensor chip version. Signed-off-by:

Add controls for horizontal and vertical blanking. Also add an error message for case that the control handler init failed. Since setting the blanking registers is done by controls now, we shouldn't change these registers outside of the control function. Use v4l2_ctrl_s_ctrl() to set them. Signed-off-by:

The mx1_camera driver has been broken for a few release cycles since commit 6bd08127 (dmaengine: imx-dma: merge old dma-v1.c with imx-dma.c). It seems there is no one even compile tested it since then, as doing so will end up with the following error. CC drivers/media/platform/soc_camera/mx1_camera.o In file included from drivers/media/platform/soc_camera/mx1_camera.c:44:0: arch/arm/mach-imx/include/mach/dma-mx1-mx2.h:8:25: fatal error: mach/dma-v1.h: No such file or directory It seems there is no one being interested in bringing it back to work [1] so far.

The winbond hardware has a counter for leading edges, which increases as they are received. As we read raw IR from a fifo in an interrupt handler, we cannot correlate them to specific IR pulses so we simply count all pulses and edges until we go idle and disable the receiver. Signed-off-by:

The receiver is never disabled by idle mode since rxstate never gets set to RXSTATE_ACTIVE, so we keep on getting interrupts after the first IR activity ends. Note that ir_raw_event_reset() already calls ir_raw_event_handle(). Signed-off-by:
