usb: bdc: Halt controller on suspend

2020-08-19T06:26:21Z

[ Upstream commit 5fc453d7de3d0c345812453823a3a56783c5f82c ] GISB bus error kernel panics have been observed during S2 transition tests on the 7271t platform. The errors are a result of the BDC interrupt handler trying to access BDC register space after the system's suspend callbacks have completed. Adding a suspend hook to the BDC driver that halts the controller before S2 entry thus preventing unwanted access to the BDC register space during this transition.

bdc: Fix bug causing crash after multiple disconnects

2020-08-19T06:26:21Z

[ Upstream commit a95bdfd22076497288868c028619bc5995f5cc7f ] Multiple connects/disconnects can cause a crash on the second disconnect. The driver had a problem where it would try to send endpoint commands after it was disconnected which is not allowed by the hardware. The fix is to only allow the endpoint commands when the endpoint is connected. This will also fix issues that showed up when using configfs to create gadgets.

If this is in "transceiver" mode the the ->qwork isn't required and is a NULL pointer. This can lead to a NULL dereference when we call destroy_workqueue(udc->qwork). Fixes: 3517c31a8ece ("usb: gadget: mv_udc: use devm_xxx for probe") Signed-off-by: Dan Carpenter Signed-off-by: Felipe Balbi

Felipe writes: USB: changes for v5.8 merge window Rather busy cycle. We have a total 99 non-merge commits going into v5.8 merge window. The majority of the changes are in dwc3 this around (31.7% of all changes). It's composed mostly Thinh's recent updates to get dwc3 to behave correctly with stream transfers. We have also have Roger's for Keystone platforms and Neil's updates for the meson glue layer. Apart from those, we have the usual set of non-critical fixes, new device IDs, spelling fixes all over the place.

If the function "platform_get_irq()" failed, the negative value returned will not be detected here, including "-EPROBE_DEFER", which causes the application to fail to get the correct error message.
