Subject[PATCH AUTOSEL 5.10 060/137] ice: fix clang warning regarding deadcode.DeadStores
Date
From: Paul M Stillwell Jr <paul.m.stillwell.jr@intel.com>

[ Upstream commit 7e94090ae13e1ae5fe8bd3a9cd08136260bb7039 ]

clang generates deadcode.DeadStores warnings when a variable
is used to read a value, but then that value isn't used later
in the code. Fix this warning.
