Subject: [PATCH 4.19 134/323] media: si470x: Avoid card name truncation

From: Kees Cook <keescook@...omium.org>

[ Upstream commit 2908249f3878a591f7918368fdf0b7b0a6c3158c ]

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, "Silicon Labs Si470x FM Radio Re".
