Remove casting the values returned by memory allocation functions like kmalloc, kzalloc, kmem_cache_alloc, kmem_cache_zalloc etc. Semantic patch information: This makes an effort to find cases of casting of values returned by kmalloc, kzalloc, kcalloc, kmem_cache_alloc, kmem_cache_zalloc, kmem_cache_alloc_node, kmalloc_node and kzalloc_node and removes the casting as it is not required. The result in the patch case may need some reformatting. Generated by: scripts/coccinelle/api/alloc/alloc_cast.cocci Signed-off-by:

Files input_formatter_subsystem_defs.h begin with: #ifndef _if_subsystem_defs_h #define _if_subsystem_defs_h__ and end with: #endif /* _if_subsystem_defs_h__ */ The intent seems to have been to use _if_subsystem_defs_h__ everywhere but two underscores are missing in the initial #ifndef.

Use tabs in Kconfig for indentation rather than spaces. The patch has been created using the following command: find drivers/staging/media/atomisp/ -name Kconfig| \ xargs perl -i -pe 's/ {8}/\t/g' Signed-off-by: -

The help text should be indented by at least two spaces after the 'help' separator. This is both good practice and the media_build system for building media drivers makes this assumption. Fix this for the atomisp/i2c/Kconfig and fix the atomisp/pci/Kconfig that didn't align the help separator with the preceding keywords. Signed-off-by:

Hans Verkuil authored
The help text should be indented by at least two spaces after the 'help' separator. This is both good practice and the media_build system for building media drivers makes this assumption. I went through all Kconfigs under drivers/media and fixed any bad help sections. This makes it conform to the common practice and should fix problems with 'make menuconfig' when using media_build. This is due to a "WARNING" message that media_build can insert in the Kconfig and that assumes the help text is indented by at least two spaces. If not, then the Kconfig becomes invalid and 'make menuconfig' fails. Signed-off-by:

In the distant past the adv7604 driver used private controls. In order to access them the v4l-subdevX nodes were needed. Later the is_private tag was removed in the adv7604 driver and the need for v4l-subdevX device nodes disappeared. Remove the creation of those device nodes from this driver. Note: the cobalt card is only used inside Cisco and we never actually used the v4l-subdevX nodes for anything. So this API change can be done safely without breaking anything. Signed-off-by:

Hans Verkuil authored
Add a simple HDMI CEC GPIO driver that sits on top of the cec-pin framework. While I have heard of SoCs that use the GPIO pin for CEC (apparently an early RockChip SoC used that), the main use-case of this driver is to function as a debugging tool. By connecting the CEC line to a GPIO pin on a Raspberry Pi 3 for example it turns it into a CEC debugger and protocol analyzer. With 'cec-ctl --monitor-pin' the CEC traffic can be analyzed. But of course it can also be used with any hardware project where the HDMI CEC line is hooked up to a pull-up gpio line. In addition this has (optional) support for tracing HPD changes if the HPD is connected to a GPIO. Signed-off-by:
