Subject: [PATCH] media: tuners: fc0013 Remove unused functions
Date: Sat, 16 Nov 2024 15:16:31 +0000 [thread overview]
Message-ID: <20241116151631.95706-1-linux@treblig.org> (raw)
From: "Dr. David Alan Gilbert" <linux@treblig.org>
fc0013_rc_cal_add() and fc0013_rc_cal_reset() were added in 2012's
commit e889adc91187 ("[media] fc001x: tuner driver for FC0013")
but haven't been used.
Remove them.
