SubjectRe: [PATCH v6 1/7] pinctrl: rockchip: add suspend/resume functions
Date
Hi Chris,

I've now applied patches 1 and 2 of your series to my v3.19-pinctrl/next
branch and will be sending a pull request to LinusW shortly.

So _if_ a v7 becomes necessary you don't need to include these two patches
anymore.


Heiko
