From 619ab8f611e269e12c956361a38a4206cef9155d Mon Sep 17 00:00:00 2001 From: Fengguang Wu Date: Sat, 20 Apr 2013 06:02:16 -0300 Subject: [PATCH] [media] r820t: quiet gcc warning on n_ring drivers/media/tuners/r820t.c: In function 'r820t_imr': drivers/media/tuners/r820t.c:1871:8: warning: 'n_ring' may be used uninitialized in this function [-Wmaybe-uninitialized] Mauro: This is a FALSE POSITIVE: the loop will always return a value for n_ring, as the last test will fill it with 15, if the loop fails.
