Subject: [PATCH] iio: buffer: Remove redundant assignment to in_loc
Date: Mon, 17 May 2021 18:11:57 +0800 [thread overview]
Message-ID: <1621246317-62725-1-git-send-email-jiapeng.chong@linux.alibaba.com> (raw)
Variable in_loc is being assigned a value from a calculation
however the assignment is never read, so this redundant assignment
can be removed.
Clean up the following clang-analyzer warning:
drivers/iio/industrialio-buffer.c:929:3: warning: Value stored to
'in_loc' is never read [clang-analyzer-deadcode.DeadStores].
