ARM: 6653/1: bitops: Use BX instead of MOV PC,LR
The kernel doesn't officially need to interwork, but using BX wherever appropriate will help educate people into good assembler coding habits. BX is appropriate here because this code is predicated on __LINUX_ARM_ARCH__ >= 6 Signed-off-by: Dave Martin <dave.martin@linaro.org> Acked-by: Nicolas Pitre <nicolas.pitre@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
