<content type='text'>
commit bbf0a94744edfeee298e4a9ab6fd694d639a5cdf upstream.

A rx flow control waiting in the control queue may block autosuspend.
Re-request autosuspend after flow control been sent to unblock
the transition to the low power state.

commit bcbc0b2e275f0a797de11a10eff495b4571863fc upstream.

A receive callback is queued while the client is still connected
but can still be called after the client was disconnected. Upon
disconnect cl-&gt;me_cl is set to NULL, hence we need to check
that ME client is not-NULL in mei_cl_mtu to avoid
null dereference.

<id>urn:sha1:62dd03054918ff7ad7e8c0a4197e1b61d033be4c</id>
<content type='text'>
commit e852c2c251ed9c23ae6e3efebc5ec49adb504207 upstream.

It's not needed to set driver to NULL in mei_cl_device_remove()
which is bus_type remove() handler as this is done anyway
in __device_release_driver().

Actually this is causing an endless loop in driver_detach()
on ubuntu patched kernel, while removing (rmmod) the mei_hdcp module.
The reason list_empty(&amp;drv-&gt;p-&gt;klist_devices.k_list) is always not-empty.
as the check is always true in  __device_release_driver()
	if (dev-&gt;driver != drv)
		return;

The non upstream patch is causing this behavior, titled:
'vfio -- release device lock before userspace requests'

Nevertheless the fix is correct also for the upstream.
