Subject: USB: bcma: use simpler devm helper for getting vcc GPIO
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1507372b97a098fd51b92c4dbdbbcd65cba26939;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

USB: bcma: use simpler devm helper for getting vcc GPIO

Thanks to switching to devm_gpiod_get:
1) We don't have to pass fwnode pointer
2) We can request initial GPIO value at getting call
This was successfully tested on Netgear R6250 (BCM4708).
