RE: linux-next: build failure after merge of the imx-mxs tree

[Anson Huang]

Hi, Stephen/Shawn
	I realized this issue last week when I updated my Linux-next tree (NOT sure why I did NOT meet such issue when I did the patch), so I resent the patch series of adding head file "io.h" to fix this issue, please apply below V2 patch series instead, sorry for the inconvenience.

https://patchwork.kernel.org/patch/10944681/

thanks,
Anson.
