Subject: MIPS: uprobes: remove set but not used variable 'epc'
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=77862490bd9cf624da74c2449141d97ca644c282;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

MIPS: uprobes: remove set but not used variable 'epc'

[ Upstream commit f532beeeff0c0a3586cc15538bc52d249eb19e7c ]

Fixes gcc '-Wunused-but-set-variable' warning:

arch/mips/kernel/uprobes.c: In function 'arch_uprobe_pre_xol':
arch/mips/kernel/uprobes.c:115:17: warning: variable 'epc' set but not used [-Wunused-but-set-variable]

It's never used since introduction in
commit 40e084a506eb ("MIPS: Add uprobes support.")
