From eb1852b10593dc3ca73e02bf9ac4753a5a464905 Mon Sep 17 00:00:00 2001 From: "John W. Linville" Date: Mon, 21 Nov 2011 16:37:26 -0500 Subject: [PATCH] rtlwifi: squash warning in _usb_read_sync MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit drivers/net/wireless/rtlwifi/usb.c: In function ‘_usb_read_sync’: drivers/net/wireless/rtlwifi/usb.c:102:6: warning: ‘status’ may be used uninitialized in this function drivers/net/wireless/rtlwifi/usb.c:102:6: note: ‘status’ was declared here My compiler is dumb, but better to eliminate the warning than to have anyone waste time evaluating this again...
