Subject: [PATCH] tile: remove compat_sys_lookup_dcookie declaration to fix
compile error
commit 5a5e75f4714a592f31e57f248b8f5c866f278b8d upstream.
With commit d8d14bd09cdd ("fs/compat: fix lookup_dcookie() parameter
handling") I changed the type of the len parameter of the
lookup_dcookie() syscall.
However I missed that there was still a stale declaration in
arch/tile/.. which now causes a compile error on tile:
In file included from fs/dcookies.c:28:0:
include/linux/compat.h:425:17: error: conflicting types for 'compat_sys_lookup_dcookie'
fs/dcookies.c:207:1: error: conflicting types for 'compat_sys_lookup_dcookie'
Simply remove the declaration in the tile architecture, which is only a
leftover from before the different compat lookup_dcookie() versions have
been merged. The correct declaration is now in include/linux/compat.h
The build error was reported by Fenguang's build bot.
