Subject: [PATCH v3 0/2] USB: serial: use wrappers for usb_control_msg()

There are many usages of usb_control_msg() that can instead use the new
wrapper functions usb_contro_msg_send() & usb_control_msg_recv() for
better error checks on short reads. The wrappers also handle the
allocation of dma buffers and callers don't need to manage them
explicitly.

This is a follow up on v2 with 6 patches. 4 of them are already applied
so v3 only includes the two remaining patches. The patches are
compile-tested only.

Changes in v3:
 - Rephrase commit messages
 - Add notes on omitting the logs for short read sizes

Changes in v2:
 - Drop unnecessary use of wrappers
 - Drop unrelated style changes

Himadri Pandya (2):
  USB: serial: ch314: use usb_control_msg_recv() and
    usb_control_msg_send()
  USB: serial: cp210x: use usb_control_msg_recv() and
    usb_control_msg_send()
