From 388cebfa7342cbf0ad5522c570d7630f241ebeac Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 3 Aug 2021 21:46:10 +0200 Subject: [PATCH] media: tm6000: Avoid card name truncation [ Upstream commit 42bb98e420d454fef3614b70ea11cc59068395f6 ] The "card" string only holds 31 characters (and the terminating NUL). In order to avoid truncation, use a shorter card description instead of the current result, "Trident TVMaster TM5600/6000/60".
