Subject: usb: dwc3: omap: Replace the extcon API
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c773bb0b9264206958a8d1e032baaa57ec66c22c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

usb: dwc3: omap: Replace the extcon API

This patch uses the resource-managed extcon API for extcon_register_notifier()
and replaces the deprecated extcon API as following:
- extcon_get_cable_state_() -> extcon_get_state()
