    Subject[PATCH 4.14 21/51] MIPS: uprobes: remove set but not used variable epc
    Date
    [ 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.")
