USB-serial drivers must not be unbound from their ports before the corresponding USB driver is unbound from the parent interface so suppress the bind and unbind attributes. Unbinding a serial driver while it's port is open is a sure way to trigger a crash as any driver state is released on unbind while port hangup is handled on the parent USB interface level.

commit 9c06ac4c83df6d6fbdbf7488fbad822b4002ba19 upstream.

If hub_activate() is called before D+ has stabilized after remote
wakeup, the following situation might occur:

         __      ___________________

D+   __/    \__/

          |  |    \-- ClearPortFeature (*2)
          |   \-- GetPortStatus (*1)
          \-- Host detects remote wakeup

- D+ goes high, Host starts running by remote wakeup
- D+ is not stable, goes low
- Host requests GetPortStatus at (*1) and gets the following hub status:
  - Current Connect Status bit is 0
  - Connect Status Change bit is 1
- D+ stabilizes, goes high
- Host requests ClearPortFeature and thus Connect Status Change bit is
  cleared at (*2)
- After waiting 100 ms, Host starts the Interrupt Transfer at (*3)
- Since the Connect Status Change bit is 0, Hub returns NAK.

In this case, port_event() is not called in hub_event() and Host cannot
recognize device. To solve this issue, flag change_bits even if only
Connect Status Change bit is 1 when got in the first GetPortStatus.

This issue occurs rarely because it only if D+ changes during a very
short time between GetPortStatus and ClearPortFeature. However, it is
fatal if it occurs in embedded system.

usb: musb: dma: Correct parameter passed to IRQ handler 2020-04-28T18:03:12+00:00 Paul Cercueil paul@crapouillou.net 2019-12-16T16:18:43+00:00 d2b540216a5408fef451ee377e6fd719daf4dc1a commit c80d0f4426c7fdc7efd6ae8d8b021dcfc89b4254 upstream. The IRQ handler was passed a pointer to a struct dma_controller, but the argument was then casted to a pointer to a struct musb_dma_controller.

commit c80d0f4426c7fdc7efd6ae8d8b021dcfc89b4254 upstream.

The IRQ handler was passed a pointer to a struct dma_controller, but the
argument was then casted to a pointer to a struct musb_dma_controller.
