Subject: [PATCH] [media] cx23885: Remove unused netup_eeprom_write
Date: Thu, 20 Feb 2025 15:02:38 +0000 [thread overview]
Message-ID: <20250220150238.77737-1-linux@treblig.org> (raw)
From: "Dr. David Alan Gilbert" <linux@treblig.org>
netup_eeprom_write() was added in 2009 by
commit b45c0551f94d ("V4L/DVB (10797): Add EEPROM code for NetUP Dual
DVB-S2 CI card.")
but has remained unused.
Remove it.
