Subject: Input: ad7879 - convert I2C to dev_pm_ops
X-Git-Tag: v2.6.38-rc1~247^2^2~10
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d5dc9ac3f6daf7df45c49e5a861c733a5f794c6b;p=karo-tx-linux.git

Input: ad7879 - convert I2C to dev_pm_ops

There is a general move towards the use of dev_pm_ops rather than
bus specific suspend APIs as this simplifies both the bus and PM core
implementations. Convert the ad7879-ts I2C support over.

Compile tested only.
