[ARM] 5231/1: Do not save the frame pointer in the csum_partial_copy_* functions
Since the other assembly functions do not seem to save the frame pointer onto the stack, this patch changes the csum_partial_copy_* functions to behave in the same way. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
