[PATCH 0/4] remove devm_pinctrl_get_select_default from drivers

[PATCH 0/4] remove devm_pinctrl_get_select_default from drivers

[Wolfram Sang]

The core does this automatically, no need to do this explicitly in drivers.
Those patchces should go via the respective subtrees. Thanks!

[PATCH 2/4] drivers/mmc/host: don't use devm_pinctrl_get_select_default() in probe

[Wolfram Sang]

Since commit ab78029 (drivers/pinctrl: grab default handles from device core),
we can rely on device core for setting the default pins. Compile tested only.

This new line does not belong to this patch.
