From 9e5f1721907fcfbd4b575bcafa0314188f7330a5 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 14 Oct 2013 15:28:38 +0300 Subject: [PATCH] yam: integer underflow in yam_ioctl() We cap bitrate at YAM_MAXBITRATE in yam_ioctl(), but it could also be negative. I don't know the impact of using a negative bitrate but let's prevent it. Signed-off-by: Dan Carpenter Signed-off-by: David S.
