From f491dbe049cc7d8fb4c1cdc7d9fdfac0d1d99869 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 27 Oct 2014 02:25:00 -0300 Subject: [PATCH] [media] dvb-net: Fix probable mask then right shift defects Precedence of & and >> is not the same and is not left to right. shift has higher precedence and should be done after the mask. Add parentheses around the mask.
