Subject: [PATCH] drivers: net: xgene: Add missing initialization in xgene_enet_ecc_init()
Date: Mon, 20 Oct 2014 10:08:16 +0200	[thread overview]
Message-ID: <1413792496-8558-1-git-send-email-geert@linux-m68k.org> (raw)

drivers/net/ethernet/apm/xgene/xgene_enet_sgmac.c: In function ‘xgene_enet_ecc_init’:
drivers/net/ethernet/apm/xgene/xgene_enet_sgmac.c:126: warning: ‘data’ may be used uninitialized in this function

Depending on the arbitrary value on the stack, the loop may terminate
too early, and cause a bogus -ENODEV failure.
