Subject: [PATCH 00/25] Change tty_port(standard)_install's return type
Date: Tue,  4 Sep 2018 11:44:26 +0900	[thread overview]
Message-ID: <1536029091-4426-1-git-send-email-climbbb.kim@gmail.com> (raw)

Many drivers with tty use the tty_stand_install(). But, there is no
need to handle the error, since it always returns 0. So, change the
return type of tty_standard_install() and tty_port_install() to void
type and remove unnecessary exception handling where we use these
functions.

Change return type for tty functions. Patch No.01
  tty: Change return type to void

Apply tty_port_install() changes. Patch No.02~14
  isdn: i4l: isdn_tty: Change return type to void
  ...
  Bluetooth: Change return type to void

Apply tty_standard_install() changes. Patch No.15~25
  um: Change return type to void
  ...
  usb: usb-serial: Change return type to void
