Subject: media: saa7134: fix terminology around saa7134_i2c_eeprom_md7134_gate()
Author: Maciej S. Szmigiero <m...@maciej.szmigiero.name>
Date: Tue Aug 20 19:05:55 2019 -0300
saa7134_i2c_eeprom_md7134_gate() function and the associated comment uses
an inverted i2c gate open / closed terminology.
Let's fix this.
