parisc: Avoid compiler warnings with access_ok()
Commit 09b871ffd4d8 (parisc: Define access_ok() as macro) missed to mark uaddr as used, which then gives compiler warnings about unused variables. Fix it by comparing uaddr to uaddr which then gets optimized away by the compiler. Signed-off-by: Helge Deller <deller@gmx.de> Fixes: 09b871ffd4d8 ("parisc: Define access_ok() as macro")
