[ 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.")
