checkpatch: don't ask for asm/file.h to linux/file.h unconditionally
Currently checkpatch warns when asm/file.h is included and linux/file.h exists. That conversion can be made when linux/file.h includes asm/file.h which is not always the case.(See signal.h) Signed-off-by: Fabian Frederick <fabf@skynet.be> Cc: Andy Whitcroft <apw@canonical.com> Acked-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
