Subject: x86/fpu: Rename copy_fpstate_to_fpregs() to copy_kernel_to_fpregs()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3e1bf47e5c81c2b895db4bea67f70c3ca8e5b984;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

x86/fpu: Rename copy_fpstate_to_fpregs() to copy_kernel_to_fpregs()

Bring the __copy_fpstate_to_fpregs() and copy_fpstate_to_fpregs() functions
in line with the naming of other kernel-to-FPU-registers copying functions.
