The media_device structure abstracts functions common to all kind of media devices (v4l2, dvb, alsa, ...). It manages media entities and offers a userspace API to discover and configure the media device internal topology. Signed-off-by:

The media_devnode structure provides support for registering and unregistering character devices using a dynamic major number. Reference counting is handled internally, making device drivers easier to write without having to solve the open/disconnect race condition issue over and over again. The code is based on video/v4l2-dev.c. [mchehab@redhat.com: Remove linux/smp_lock.h include to not break compilation on bisect] Signed-off-by:

Provide v4l2_subdevs with v4l2_event support. Subdev drivers only need very little to support events. Signed-off-by:

Create a device node named subdevX for every registered subdev. As the device node is registered before the subdev core::s_config function is called, return -EGAIN on open until initialization completes. Signed-off-by:

There's no reason to require subdevices to implement the core operations. Remove the check for non-NULL core operations when initializing the subdev. Signed-off-by:

The two functions are mostly identical. They handle the copy_from_user and copy_to_user operations related with V4L2 ioctls and call the real ioctl handler. Create a __video_usercopy function that implements the core of video_usercopy and video_ioctl2, and call that function from both. Signed-off-by:

Out of the three files accessing the device list, one uses a mutex, one uses the BKL and one does not have any locking. That is of course pointless, so let's make all of them use the same mutex, and get rid of one more BKL user. Signed-off-by:

Related to Acorp DS120 and some revisions of DVBWorld DW2102. If you read three or more registers at one time, you get wrong value for third etc. Actually, it didn't affect the driver as it reads registers only by one at a time. But it needs to correct. Signed-off-by:

These changes are needed to keep up with the changes in the MFD core and V4L2 parts of the wl1273 FM radio driver. Use function pointers instead of exported functions for I2C IO. Also move all preprocessor constants from the wl1273.h to include/linux/mfd/wl1273-core.h. Also update the year in the copyright statement. Signed-off-by:

This is the core of the WL1273 FM radio driver, it connects the two child modules. The two child drivers are drivers/media/radio/radio-wl1273.c and sound/soc/codecs/wl1273.c. The radio-wl1273 driver implements the V4L2 interface and communicates with the device. The ALSA codec offers digital audio, without it only analog audio is available. Signed-off-by:

kmalloc() can fail so check whether state->internal is NULL. append_internal() can return NULL on allocation failures so check that. Also if we hit the error condition later in the function then there is a memory leak and we need to call remove_dev() to fix it. Also Oliver Endriss pointed out an additional leak that I missed in the first version of this patch. Signed-off-by:
