Subject: USB: serial: cp210x: Fixed usb_control_msg timeout values
From: Yuri Matylitski <[email protected]>
commit 2d5733fcd33dd451022d197cb6b476e970519ca7 upstream.
Fixed too small hardcoded timeout values for usb_control_msg
in driver for SiliconLabs cp210x-based usb-to-serial adapters.
Replaced with USB_CTRL_GET_TIMEOUT/USB_CTRL_SET_TIMEOUT.
