Subject: [ARM] 5231/1: Do not save the frame pointer in the csum_partial_copy_* functions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=22acc4e65043d436bc286e6059960fa533e37356;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[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.
