[PATCH 00/25] Change tty_port(standard)_install's return type

From: Jaejoong Kim
Date: Mon Sep 03 2018 - 22:45:06 EST


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
