[v1,1/2] pinctrl: Get rid of duplicate of_node assignment in the drivers

Commit Message

Andy Shevchenko Dec. 13, 2021, 4:39 p.m. UTC

GPIO library does copy the of_node from the parent device of
the GPIO chip, there is no need to repeat this in the individual
drivers. Remove these assignment all at once.

For the details one may look into the of_gpio_dev_init() implementation.

Thanks, there is v2 with this patch w/o changes. I take a liberty to
extrapolate the tags to it. I need to send a v3 in case Linus hasn't
taken the first patch before it happens.
