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>

/*

* The low level init and interrupt stuff is handled in arch/mm68k/atari/atakeyb.c
|
|
* (the keyboard ACIA also handles the mouse and joystick data, and the keyboard
|
|
* interrupt is shared with the MIDI ACIA so MIDI data also get handled there).
|
|
* This driver only deals with handing key events off to the input layer.
|
|
*
|
|
* Largely based on the old:

|
* Atari Mouse Driver for Linux
|
|
* by Robert de Vries (robert@and.nl) 19Jul93
|
|
*
|
|
* 16 Nov 1994 Andreas Schwab
|
|
* Compatibility with busmouse
|
|
* Support for three button mouse (shamelessly stolen from MiNT)
|
|
* third button wired to one of the joystick directions on joystick 1
|
|
*
|
|
* 1996/02/11 Andreas Schwab
|
|
* Module support
|
|
* Allow multiple open's
|
|
*
|
|
* Converted to use new generic busmouse code. 5 Apr 1998
