[PATCH v7 0/4] usb/gadget: independent registration of gadgets and gadget drivers

From: Marek Szyprowski
Date: Mon Nov 23 2015 - 03:57:19 EST


This is a resurrection of the patches initially submitted by Ruslan
Bilovol in the following thread: https://lkml.org/lkml/2015/6/22/554

The changes since the original submission (v5) includes rebase onto
latest linux-next branch, simplification of the code requested by Alan
Stern and Felipe Balbi, removal of a patch, which deleted __init/__exit
attributes (this change has been already merged) and fixes of the
checkpatch issues.

This feature is urgently needed, because it is not longer possible to
use workaround to avoid deferred probe in UDC drivers due to
not-yet-probed i2c regulator drivers (for more information see
https://lkml.org/lkml/2015/10/30/374 ).

This patchset has been successfully tested on Odroid XU3 boards with
DWC3 UDC driver being deferred by missing regulator drivers.
