From 254f02e17d182c43370c17d5c7fd5bdda531f3d8 Mon Sep 17 00:00:00 2001 From: "Maciej S. Szmigiero" Date: Tue, 20 Aug 2019 19:05:55 -0300 Subject: [PATCH] media: saa7134: fix terminology around saa7134_i2c_eeprom_md7134_gate() [ Upstream commit 9d802222a3405599d6e1984d9324cddf592ea1f4 ] saa7134_i2c_eeprom_md7134_gate() function and the associated comment uses an inverted i2c gate open / closed terminology. Let's fix this. Signed-off-by: Maciej S.
