Subject: [PATCH] xhci: correct the usage of USB_CTRL_SET_TIMEOUT
The usage of USB_CTRL_SET_TIMEOUT is incorrect. The
definition of USB_CTRL_SET_TIMEOUT is 5000ms. The
input timeout to wait_for_completion_interruptible_timeout
is jiffies. That makes the timeout be longer than what
we want, such as 50s in some platform.
The patch is to convert USB_CTRL_SET_TIMEOUT to jiffies as
command completion event timeout.
