+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).
