This USB CCID function driver will be a transport layer between the
userspace CCID component and the Windows Host. Data and control
commands from the Windows Host will be sent to the userspace component
and vice-versa. This snapshot is taken as of msm-4.19 commit 104eef6e1fe8
("platform: msm: Remove unused local count variable").

The spss-util driver provides utilities required for the Secure
Processor Subsystem (SPSS). It provides the fuse state for key selection
and the SPSS HW version.

If cable disconnects before data stage completion dwc3_remove_requests()
gets called for ep0 in and out but dwc3_ep0_complete_data() does not
get called. dwc3_ep0_complete_data() function resets TRB enqueue count
to 0. As a result upon next cable connect start transfer is called with
wrong TRB address because trb_enqueue is set to 1. Since this TRB was
completed in the past, HWO bit is cleared for this TRB. This results into
usb enumeration failure due to control transfer stall. Fix this issue
by issuing end transfer command on control endpoints after ep0 requests
are removed for IN and OUT and reset trb_enqueue counters to 0.

Consider a case of quick pull-up disable after pull-up is enabled.
If a SETUP packet comes after bus reset event followed by connection
done event, there is a possibility of race between
composite_dev_cleanup() freeing cdev->req called from
configfs_composite_unbind() and composite_setup() storing req pointer
to stack. This causes use after free of cdev->req. Fix this issue by
disabling the irq before clearing the run-stop bit so that interrupt
handling for setup packet is prevented. In order to prevent running
bottom half check pullups_connected flag in dwc3_interrupt and ack
the generated events and return. Also flush the bottom half work
if there was any work pending before disabling dwc3 irq.

gadget_driver can become null if gadget_stop is called while any other
gadget callbacks are in progress. As gadget callbacks needs to release
spinlock before the callback, store the local copy of gadget_driver to
avoid the race with gadget_stop.

Spurious suspend event may arrive before CONNECT DONE, which
may unnecessarily notify to the charger to reduce current
draw to 2mA, only to revert back to 100mA on the subsequent
reset & connection. Instead, only enable the SUSPEND event
interrupt after the initial CONNECT DONE event is handled.

debugfs_create_dir() returns NULL when second directory is created
with same name gsi-epin. Without checking return value
dwc3_debugfs_create_endpoint_dir() creates endpoint files with parent
as NULL. This would create files in root dir /sys/kernel/debug which
remains there even after calling debugfs_remove_recursive() from
dwc3_debugfs_exit(). Due to probe deferral dwc3 endpoints get freed
up and re-allocated. As a result accessing endpoint files created in
root dir causes access to stale dwc3 endpoint pointer. Hence check
return value for debugfs_create_dir and do not create files for NULL
parent.
