Subject: [PATCH RFT/RFC 21/49] staging: media: zoran: Use video_drvdata to get struct zoran
Date:   Mon, 21 Sep 2020 10:19:56 +0000
Message-Id: <1600683624-5863-22-git-send-email-clabbe@baylibre.com>
In-Reply-To: <1600683624-5863-1-git-send-email-clabbe@baylibre.com>
References: <1600683624-5863-1-git-send-email-clabbe@baylibre.com>
Precedence: bulk

Using video_drvdata() is proper and shorter than using directly
fh pointers.
