Subject: bpf, arm: Remove unused function emit_a32_alu_r()
X-Git-Tag: v6.1-rc5~731^2~339^2~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fc386ba7211d514f2c20285cb6b9b502618634e0;p=platform%2Fkernel%2Flinux-starfive.git

bpf, arm: Remove unused function emit_a32_alu_r()

Since commit b18bea2a45b1 ("ARM: net: bpf: improve 64-bit ALU implementation")
this is unused anymore, so can remove it.
