Subject[PATCH v3 0/2] usb: dwc3: drd: Check graph presence for extcon
Date
dwc3 shows error message on probe if port node wasn't found in PHY
controller node. But that is actually a valid case for the role switch
mode and OTG mode. This patch series makes sure to hide that error
message and also does a bit of refactoring for that code. Similar patch
(for different subsystem) already exists in kernel tree:
commit ea5bc3b15e0f ("drm/of: Make drm_of_find_panel_or_bridge() to
check graph's presence"), and the whole `of_graph_is_present()' function
was implemented exactly for this kind of situation.

In previous submission (v2) it was a single patch. But in offline
discussion with Andy Shevchenko it was decided it's better to split it
into two patches in order to provide the minimal change for further
possible backporting, and do all style related changes on top of it in
second patch.

Sam Protsenko (2):
usb: dwc3: drd: Avoid error when extcon is missing
usb: dwc3: drd: Improve dwc3_get_extcon() style
