Subject: V4L/DVB: saa7134: get rid of I2C_HW_SAA7134
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c72ba8e6ae7376d20e509a9a54a2dd45fb483fc2;p=openwrt%2Fstaging%2Fblogic.git

V4L/DVB: saa7134: get rid of I2C_HW_SAA7134

The only reason for keeping I2C_HW_SAA7134 is to allow setting a
per-device polling interval. Just move this info to the platform
data, allowing drivers to change it per device, where needed.
