Integrate the v4l2_prio_state into the core, ready for use. One struct v4l2_prio_state is added to v4l2_device and a pointer to a prio state is added to video_device. Signed-off-by:

We are going to move priority handling into the v4l2 core. As a consequence the v4l2_prio helper functions need to be moved into the core videodev module as well to prevent circular dependencies. Signed-off-by:

On my AverMedia AverTV Studio 507, key up events are no longer sent after a suspend-to-disk/resume cycle, resulting in "stuck" keys. Apparently, for key up events to be generated, a certain GPIO pin must be set. Currently it's set in saa7134_input_init1(), but that function is not called on device resume. I suggest that code be moved to __saa7134_ir_start(), which is called both on init and resume. Signed-off-by:

We use err to store negative error codes so it should be signed. And if we return an error from stv0367_get_tuner_freq() that needs to be handled properly as well. (param->frequency is a u32). Signed-off-by:

The code that checks the OLPC serial port is never built at the moment, because CONFIG_OLPC_XO_1_5 doesn't exist and probably won't be added. Fix it so that it gets compiled in, only executes on OLPC laptops, and move the check into the probe routine. The compiler is smart enough to eliminate this code when CONFIG_OLPC=n (due to machine_is_olpc() always returning false). Signed-off-by:

It makes a lot of sense. Changing it is not a problem :) How about the updated patch below? If the memory allocation to 'state' succeeds but we jump to the 'error' label before 'state' is assigned to fe->tuner_priv, then the call to 'zl10036_release(fe)' at the 'error:' label will not free 'state', but only what was previously assigned to 'tuner_priv', thus leaking the memory allocated to 'state'. This patch fixes the leak and also does not jump to 'error:' before mem has been allocated but instead just returns. Also some small style cleanups.

mem->dma_handle is a dma address obtained by dma_alloc_coherent which needn't be a physical address in presence of IOMMU, as a hardware IOMMU can (and most likely) will return a bus address where physical != bus address. So ensure we are remapping (remap_pfn_range) the right page in __videobuf_mmap_mapper by using virt_to_phys(mem->vaddr) and not mem->dma_handle. While at it, use PFN_DOWN instead of explicit shift.

The scheme used to index format in uvc_fixup_video_ctrl() is not robust: format index is based on descriptor ordering, which does not necessarily match bFormatIndex ordering. Searching for first matching format will prevent uvc_fixup_video_ctrl() from using the wrong format/frame to make adjustments. Signed-off-by:

Patch from Ian Armstrong. I've encountered a couple of problems with the current af9015 driver as supplied with the 2.6.37 kernel, that the attached patch appears to fix. (I've generated this patch against the current v4l-dvb git). Some key-presses are lost. A key-press is only generated upon 'valid' data (buf[14] == (u8) ~buf[15]), but the buffer is wiped before this check. Sometimes the 15th byte has not been set at the time of read, so the data isn't valid & ignored. On the next poll the 15th byte has been set, but the rest of the data was wiped previously, so the data is still invalid & the key is lost. Weird repeat error, where an old key press is sometimes repeated in error. ie. button sequence '1 (pause) 2 (pause) 3 (pause) 4' generates output like '1 (pause) 2 (pause) 23 (pause) 4'. The current driver zeroes the data for the key pushed, but sometimes this data is already zero but with other bytes set suggesting a repeat code. This results in the last key being incorrectly repeated. This patch attempts to reduce the risk of a missed key-press & also stop the random repeat of an old key-press when a new key is pressed.
