Linus Torvalds 93f30c73ec Merge branch 'misc.compat' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull compat and uaccess updates from Al Viro:

 - {get,put}_compat_sigset() series

 - assorted compat ioctl stuff

 - more set_fs() elimination

 - a few more timespec64 conversions

 - several removals of pointless access_ok() in places where it was
   followed only by non-__ variants of primitives

* 'misc.compat' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (24 commits)
  coredump: call do_unlinkat directly instead of sys_unlink
  fs: expose do_unlinkat for built-in callers
  ext4: take handling of EXT4_IOC_GROUP_ADD into a helper, get rid of set_fs()
  ipmi: get rid of pointless access_ok()
  pi433: sanitize ioctl
  cxlflash: get rid of pointless access_ok()
  mtdchar: get rid of pointless access_ok()
  r128: switch compat ioctls to drm_ioctl_kernel()
  selection: get rid of field-by-field copyin
  VT_RESIZEX: get rid of field-by-field copyin
  i2c compat ioctls: move to ->compat_ioctl()
  sched_rr_get_interval(): move compat to native, get rid of set_fs()
  mips: switch to {get,put}_compat_sigset()
  sparc: switch to {get,put}_compat_sigset()
  s390: switch to {get,put}_compat_sigset()
  ppc: switch to {get,put}_compat_sigset()

Al Viro 50271d388f pi433: sanitize ioctl
a) those access_ok() are pointless
b) guarding against the ioctl number declaration changes in that
way is pointless, especially since we _know_ the size of object
we want to copy.

[folded braino fixes from Colin Ian King and Dan Carpenter]

                dev_dbg(&spi->dev, "set: illegal input param"); \
                return -EINVAL; \

affects control flow by having return statement. This is against
Linux Kernel Coding Style and should be avoided and therefore
this macro is replaced by inline code.

Additionally following 3 minor issues:

ERROR: code indent should use tabs where possible
ERROR: spaces required around that '!=' (ctx:VxV)
ERROR: space prohibited before that close parenthesis ')'

were fiexed inline.
