gpu/drm: fix a few kernel-doc "/**" mark warnings

2019-07-16T09:25:02Z

The opening comment mark "/**" is reserved for kernel-doc comments, so it will generate warnings for comments that are not kernel-doc with "make W=1".

drm: drop use of drmP.h in drm/*

2019-05-27T16:07:03Z

The use of the drmP.h header file is deprecated. Remove use from all files in drm/* so people do not look there and follow a bad example. Build tested allyesconfig,allmodconfig on x86, arm etc. Including alpha that is as always more challenging than the rest.

drm/legacy: move lock cleanup for master into lock file (v2)

drm: Differentiate the lack of an interface from invalid parameter

2018-09-14T16:29:47Z

If the ioctl is not supported on a particular piece of HW/driver combination, report ENOTSUP (aka EOPNOTSUPP) so that it can be easily distinguished from both the lack of the ioctl and from a regular invalid parameter. v2: Across all the kms ioctls we had a mixture of reporting EINVAL, ENODEV and a few ENOTSUPP (most where EINVAL) for a failed drm_core_check_feature(). Update everybody to report ENOTSUPP. v3: ENOTSUPP is an internal errno! It's value (524) does not correspond to a POSIX errno, the one we want is ENOTSUP. However, uapi/asm-generic/errno.h doesn't include ENOTSUP but man errno says "ENOTSUP and EOPNOTSUPP have the same value on Linux, but according to POSIX.1 these error values should be distinct." so use EOPNOTSUPP as its equivalent.

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:29Z

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.
