Subject: [PATCH V2] EDAC: remove set but not used variable 'ecc_loc'
Date: Mon, 16 Dec 2019 19:01:21 +0800 [thread overview]
Message-ID: <20191216110121.46698-1-yukuai3@huawei.com> (raw)
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/edac/i5100_edac.c: In function ‘i5100_read_log’:
drivers/edac/i5100_edac.c:489:11: warning: variable ‘ecc_loc’
set but not used [-Wunused-but-set-variable]
It is never used, and so can be removed.
