treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

media: radio: remove redundant assignment to variable retval

2020-08-06T09:28:21Z

The variable retval is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

media: radio: don't use a menu just for wl128x driver

2020-04-16T08:34:57Z

It doesn't make any sense to have a submenu just for this driver. Drop it. Signed-off-by: Mauro Carvalho Chehab

media: docs: move driver-specific info to driver-api

2020-04-14T08:36:18Z

Those documents don't really describe the driver API. Instead, they contain development-specific information. Yet, as the main index file describes the content of it as: "how specific kernel subsystems work from the point of view of a kernel developer" It seems to be the better fit.

media: docs: move user-facing docs to the admin guide

2020-04-14T08:34:58Z

Most of the driver-specific documentation is meant to help users of the media subsystem. Move them to the admin-guide. It should be noticed, however, that several of those files are outdated and will require further work in order to make them useful again. Signed-off-by: Mauro Carvalho Chehab

media: docs: move uAPI book to userspace-api/media

2020-04-14T08:31:49Z

Since 2017, there is an space reserved for userspace API, created by changeset 1d596dee3862 ("docs: Create a user-space API guide"). As the media subsystem was one of the first subsystems to use Sphinx, until this patch, we were keeping things on a separate place. Let's just use the new location, as having all uAPI altogether will likely make things easier for developers. Signed-off-by: Mauro Carvalho Chehab

media: Fix Kconfig indentation

2020-02-24T14:19:38Z

Adjust indentation from spaces to tab (+optional two spaces) as in coding style with command like: $ sed -e 's/^ /\t/' -i */Kconfig Signed-off-by: Krzysztof Kozlowski Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: si470x-i2c: add missed operations in remove

2019-11-10T06:28:15Z

The driver misses calling v4l2_ctrl_handler_free and v4l2_device_unregister in remove like what is done in probe failure. Add the calls to fix it. Signed-off-by: Chuhong Yuan Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: radio: wl1273: fix interrupt masking on release

2019-11-05T11:50:34Z

If a process is interrupted while accessing the radio device and the core lock is contended, release() could return early and fail to update the interrupt mask. Note that the return value of the v4l2 release file operation is ignored.

media: don't do a 31 bit shift on a signed int

2019-08-26T17:11:10Z

On 32-bits archs, a signed integer has 31 bits plus on extra bit for signal. Due to that, touching the 32th bit with something like: int bar = 1 << 31; has an undefined behavior in C on 32 bit architectures, as it touches the signal bit. This is warned by cppcheck. Instead, force the numbers to be unsigned, in order to solve this issue. Signed-off-by: Mauro Carvalho Chehab
