Subject: [PATCH 2/3] media: si470x: Avoid card name truncation
Date: Tue,  3 Aug 2021 12:46:09 -0700	[thread overview]
Message-ID: <20210803194610.326030-3-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, "Silicon Labs Si470x FM Radio Re".

Suggested-by: Hans Verkuil <hverkuil@xs4all.nl>
Fixes: 78656acdcf48 ("V4L/DVB (7038): USB radio driver for Silicon Labs Si470x FM Radio Receivers")
Fixes: cc35bbddfe10 ("V4L/DVB (12416): radio-si470x: add i2c driver for si470x")
