From e19bc863f1f45223a85935f070177eda6b422f8f Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 17 Dec 2012 04:52:48 -0300 Subject: [PATCH] [media] omap3isp: ispqueue: Fix uninitialized variable compiler warnings drivers/media/platform/omap3isp/ispqueue.c:399:18: warning: 'pa' may be used uninitialized in this function [-Wuninitialized] This is a false positive but the compiler has no way to know about it, so initialize the variable to 0. drivers/media/platform/omap3isp/ispqueue.c:445:6: warning: 'vm_page_prot' may be used uninitialized in this function [-Wuninitialized] This is a false positive and the compiler should know better. Use uninitialized_var().
