Subject: [media] af9035: use default i2c slave address for af9035 too
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=14992f0185ab8efd513d71e5a546090c2d41ffd4;p=openwrt%2Fstaging%2Fblogic.git

[media] af9035: use default i2c slave address for af9035 too

Some device vendors has forgotten set correct slave demod I2C address
to eeprom. Use default I2C address when eeprom has no address at all.
