Date: Sun, 29 Jun 2014 20:34:53 -0500 From: Vince Bridgers <vbridgers2013@...il.com> To: netdev@...r.kernel.org, davem@...emloft.net, peppe.cavallaro@...com Cc: vbridgers2013@...il.com, vbridger@...era.com Subject: [PATCH net v2 3/3] net: stmmac: Remove unneeded I/O read caught by cppcheck Cppcheck found a case where a local variable was being assigned a value, but not used. There seems to be no reason to read this register before assigning a new value, so addressing thie issue. cppcheck --force --enable=all --inline-suppr . shows ... Variable 'value' is reassigned a value before the old one has been used.
