[PATCH 5.14 391/849] media: radio-wl1273: Avoid card name truncation

From: Kees Cook <keescook@chromium.org>

[ Upstream commit dfadec236aa99f6086141949c9dc3ec50f3ff20d ]

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, "Texas Instruments Wl1273 FM Rad".
