Subject: [PATCH] atm: solos-pci: remove useless variable assignments
Date: Thu, 15 Jun 2017 14:56:21 -0500 [thread overview]
Message-ID: <20170615195621.GA5600@embeddedgus> (raw)
Value assigned to variable _data32_ at lines 1254 and 1257 is
overwritten at line 1260 before it can be used. This makes
such variable assignments useless.
