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:

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:
