[PATCH 5.10 297/575] media: tm6000: Avoid card name truncation
From: Greg Kroah-Hartman
Date: Mon Nov 15 2021 - 21:06:37 EST
From: Kees Cook <keescook@xxxxxxxxxxxx>
[ 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".
