6.14-stable review patch. If anyone has any objections, please let me know.

commit 342e4955a1f1ce28c70a589999b76365082dbf10 upstream.
wait_event_interruptible_timeout requires a timeout argument in units of jiffies. It was being called in usbtmc_get_stb with the usb timeout value which is in units of milliseconds.
Pass the timeout argument converted to jiffies.
