| * [media] saa7134: Fix crash when device is closed before streamoffSimon Farnsworth2013-10-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | pm_qos_remove_request was not called on video_release, resulting in the PM core's list of requests being corrupted when the file handle was freed. This has no immediate symptoms, but later in operation, the kernel will panic as the PM core dereferences a dangling pointer.

| * [media] s5p-jpeg: Initialize vfd_decoder->vfl_dir fieldJacek Anaszewski2013-09-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes regression introduced in commit 5c77879ff9ab9e7 "[media] v4l2-dev: add new VFL_DIR_ defines" caused by not initializing the vfl_dir field of the vfd_decoder instance of struct video_device, after the field was introduced. It precluded calling the driver's ioctls which require vfl_dir not to be equal to VFL_DIR_RX which is defined as 0 and uninitialized vfl_dir field is interpreted as such. In effect the test in the v4l_s_fmt function failed for the ioctls that expect is_tx to be false, which prevented the ioctl callbacks registered by the driver from being called.

| * [media] videobuf2-dc: Fix support for mappings without struct page in ↵Marek Szyprowski2013-09-241-5/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | userptr mode Earlier version of dma-contig allocator in user ptr mode assumed that in all cases DMA address equals physical address. This was just a special case. Commit e15dab752d4c588544ccabdbe020a7cc092e23c8 introduced correct support for converting userpage to dma address, but unfortunately it broke the support for simple dma address = physical address for the case, when given physical frame has no struct page associated with it (this happens if one use for example dma_declare_coherent api or other reserved memory approach). This commit restores support for such cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | Smatch complains about the locking here because we mix spin_lock_irq() with spin_lock_irqsave() in an unusual way. According to Smatch, it's not always clear if the IRQs are enabled or disabled when we return. It turns out this function is always called with IRQs enabled and we can just use spin_lock_irq(). It's called from __enqueue_in_driver().

| * [media] tda10071: change firmware download conditionAndreas Matthies2013-09-241-8/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reading firmware status register to detect whether firmware is running or not didn't worked 100% reliably. That register was likely set by firmware itself which means it could not contain reasonable values until firmware is up and running. Usually it just worked as some garbage value was returned accidentally but it appears that in some cases returned garbage value was 0x00 which was considered "firmware is up and running" by the driver and firmware loading was skipped leaving device to non-working state. Fix problem by removing unreliable check and let the driver keep count whether firmware is loaded or not.

As it makes not much sense to have sms-usb compiled as 'm' and sms-sdio compiled as 'y' (or vice-versa), only allow enabling debugfs if both are either 'y' or 'm'.

Printing an error message if @work wasn't in the queue is wrong.
