5.4.102 backported a lot of stuff that our WireGuard backport already did, in addition to other patches we had, so those patches were removed from that part of the series. In the process other patches were refreshed or reworked to account for upstream changes. This commit involved `update_kernel.sh -v -u 5.4`.

Subject: [PATCH] usb: dwc3: add otg properties update
|
|
|
|
During the USB certification CV9 test, if we report OTG descriptor
|
|
to test suite, it will require doing OTG test, but in fact, it does
|
|
not support OTG-compliance in dwc3 driver.
