[PATCH AUTOSEL 5.1 25/59] MIPS: uprobes: remove set but not used variable 'epc'

[Sasha Levin]

From: YueHaibing <yuehaibing@xxxxxxxxxx>

[ 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.")
