From 3e9bb2a071614f1d185740f31ac503ecba11d783 Mon Sep 17 00:00:00 2001 From: Vivek Goyal Date: Mon, 15 Nov 2010 19:32:43 +0100 Subject: block: fix amiga and atari floppy driver compile warning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Geert, my crosstool don't produce warning below. I guess this has to do something with compiler version. - Geert noticed following warning during compilation. drivers/block/amiflop.c:1344: warning: ‘rq’ may be used uninitialized in this function drivers/block/ataflop.c:1402: warning: ‘rq’ may be used uninitialized in this function - Initialize rq to NULL to fix the warning. If we can't find a suitable request to dispatch, this function should return NULL instead of a possibly garbage pointer. - Cross compile tested only. Don't have hardware to test it.
