ARM: 6621/1: bitops: remove condition code clobber for CLZ
The CLZ instruction does not alter the condition flags, so remove the "cc" clobber from the inline asm for fls(). Acked-by: Nicolas Pitre <nicolas.pitre@linaro.org> Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
