fixes sparse error: drivers/staging/lustre/lustre/libcfs/linux/linux-debug.c:149:6: error: symbol 'lbug_with_loc'redeclared with different type (originally declared at drivers/staging/lustre/lustre/libcfs/linux/../../../include/linux/libcfs/libcfs_private.h:82) - different modifiers Use the __noreturn macro instead of __attribute__((noreturn)) The macro is exactly that but its usage seems more common and it is bit more readable.
