[PATCH 07/10] mmc: mxs-mmc: copy wp_gpio in struct mxs_mmc_host

[Marek Vasut]

Dear Shawn Guo,

> It has wp_gpio copied in struct mxs_mmc_host from platform_data,

Copy wp_gpio into struct ...

> so that the use of platform_data can be limited in probe function,
> which will ease the device tree probe.
