2011-03-22[media] v4l2: use new flag to enable core priority handlingHans Verkuil8-14/+27
Rather than guess which driver supports core priority handling, require drivers that do to explicitly set the V4L2_FL_USE_FH_PRIO flag in video_device. Updated the core prio handling accordingly and set the flag in the three drivers that do. Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2011-03-22[media] ivtv: replace ugly casts with a proper container_ofHans Verkuil1-50/+50
ivtv-ioctl cast the 'void *fh' directly to 'ivtv_open_id *'. This should be done properly with a contained_of since the 'void *fh' is really a 'struct v4l2_fh *'. It worked because the v4l2_fh field is also the first field in the ivtv_open_id struct, but it is not clean code.

2011-03-22[media] v4l2-device: add kref and a release functionHans Verkuil3-0/+37
The video_device struct has proper ref counting and its release function will be called when the last user releases it. But no such support was available for struct v4l2_device. This made it hard to determine when a USB driver can release the device if it has multiple device nodes. With one device node it is easy of course, since when the device node is released, the whole device can be released. This patch adds refcounting to v4l2_device. When registering device nodes the v4l2_device refcount will be increased, when releasing device nodes it will be decreased. The (optional) release function will be called when the last device node was released. Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

Several drivers need to do something when the first filehandle is opened or the last filehandle is closed. Most implement some use count mechanism, but if they use v4l2_fh, then you can also just check if this is the only filehandle for the device node. A simple helper function can do this.

2011-03-22[media] saa7134-input: key up events not sent after suspend/resumeVadim Solomin1-10/+39
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.

2011-03-22[media] via-camera: Fix OLPC serial checkDaniel Drake1-46/+37
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).

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.

2011-03-22[media] V4L: videobuf, don't use dma addr as physicalJiri Slaby1-1/+1
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.

2011-03-22[media] af9015: enhance RCIan Armstrong2-11/+29
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.
