From ebd1699ec5f1a6f1f2df6b48fa54bc6ff790143c Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Thu, 18 Aug 2011 23:52:36 -0400 Subject: [libata] sata_sil: fix used-uninit warning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Init 'serror' to silence the following warning: drivers/ata/sata_sil.c: In function ‘sil_interrupt’: drivers/ata/sata_sil.c:453:14: warning: ‘serror’ may be used uninitialized in this function [-Wuninitialized] This is not a 'can never happen' but is nonetheless extremely unlikely. The easiest and cleanest warning fix is simply to init the var, rather than worry about marking the var uninit-ok.
