Subject: [PATCH] USB: bcma: use simpler devm helper for getting vcc GPIO
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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).
