As the code in saa7134-input is not a module, but the config for it is set as a boolean instead of a tristate, this causes a strange dependency on RC_CORE. VIDEO_SAA7134_RC (which determines if saa7134-input.o is built) depends on RC_CORE and VIDEO_SAA7134. If VIDEO_SAA7134 is compiled as 'y' but RC_CORE is compiled as 'm' VIDEO_SAA7134_RC can still be set to 'y' which causes undefined symbols that it needs from RC_CORE. The simplest solution is to not allow VIDEO_SAA7134_RC be enabled if RC_CORE compiled as a module (m) and VIDEO_SA7134 is compiled into the kernel (y). Suggested-by:

This patch fixes a bug in gspca, more precisely in alt_xfer(). This function looks for an input transfer endpoint in an alternate setting. By default it returns the first endpoint corresponding to the transfer type indicated in parameter. But with some USB devices, the first endpoint corresponding to the transfer type is not always an INPUT endpoint but an OUTPUT one. This patch adds the endpoint direction test to be sure to return an INPUT endpoint Signed-off-by:

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:

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. Signed-off-by:

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:

Drivers that use v4l2_fh can now use the core framework support of g/s_priority. Signed-off-by:

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. Signed-off-by:

Add two new functions: v4l2_fh_open allocates and initializes a struct v4l2_fh based on a struct file pointer and v4l2_fh_release releases and frees a struct v4l2_fh. Signed-off-by:

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:
