Hi!

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

[ Upstream commit 3d858942250820b9adc35f963a257481d6d4c81d ]

The event handler loop must be run with interrupts disabled.
Otherwise we will have a warning:

...

Recently xHCI driver switched to tasklets in the commit 36dc01657b49
("usb: host: xhci: Support running urb giveback in tasklet
context").

AFAICT, 36dc01657b49 is not included in 4.19.141, so this commit
should not be needed, either.

Best regards,
								Pavel
