Subject: [PATCH 1/3] media: radio-wl1273: Avoid card name truncation
Date: Tue,  3 Aug 2021 12:46:08 -0700	[thread overview]
Message-ID: <20210803194610.326030-2-keescook@chromium.org> (raw)
In-Reply-To: <20210803194610.326030-1-keescook@chromium.org>

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".

Suggested-by: Hans Verkuil <hverkuil@xs4all.nl>
Fixes: 87d1a50ce451 ("[media] V4L2: WL1273 FM Radio: TI WL1273 FM radio driver")
