4.19-stable review patch. If anyone has any objections, please let me know.

From: Linus Walleij linus.walleij@linaro.org
[ Upstream commit a6122b0b4211d132934ef99e7b737910e6d54d2f ]
This driver includes the legacy GPIO APIs <linux/gpio.h> and <linux/of_gpio.h> but does not use any symbols from any of them.
Drop the includes.
Further the driver is requesting "reset-gpios" rather than just "reset" from the GPIO framework. This is wrong because the gpiolib core will add "-gpios" before processing the request from e.g. device tree. Drop the suffix.
The last problem means that the optional RESET GPIO has never been properly retrieved and used even if it existed, but nobody noticed.
