6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luke Lu <luke.lu@libre.computer>
commit 1fa206bb764f37d2ab4bf671e483153ef0659b34 upstream.
Device connected to usb otg port of GXL-based boards can not be
recognised after resumption, doesn't recover even if disconnect and
reconnect the device. dmesg shows it disconnects during resumption.
[ 41.492911] usb 1-2: USB disconnect, device number 3
[ 41.499346] usb 1-2: unregistering device
[ 41.511939] usb 1-2: unregistering interface 1-2:1.0
Calling usb_post_init() will fix this issue, and it's tested and
verified on libretech's aml-s905x-cc board.
