get rid of input BIT* duplicate defines use newly global defined macros for input layer. Also remove includes of input.h from non-input sources only for BIT macro definiton. Define the macro temporarily in local manner, all those local definitons will be removed further in this patchset (to not break bisecting). BIT macro will be globally defined (1<<x) Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Cc: <dtor@mail.ru> Acked-by: Jiri Kosina <jkosina@suse.cz> Cc: <lenb@kernel.org> Acked-by: Marcel Holtmann <marcel@holtmann.org> Cc: <perex@suse.cz> Acked-by: Mauro Carvalho Chehab <mchehab@infradead.org> Cc: <vernux@us.ibm.com> Cc: <malattia@linux.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
