[PATCH 4/5] drivers/tty: make serial/mpsc.c driver explicitly non-modular
From: Paul Gortmaker <hidden>
Date: 2015-08-19 21:50:17
Also in:
lkml
Subsystem:
the rest, tty layer and serial drivers · Maintainers:
Linus Torvalds, Greg Kroah-Hartman, Jiri Slaby
The Kconfig for this driver is currently:
config SERIAL_MPSC
bool "Marvell MPSC serial port support"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
We leave some tags like MODULE_AUTHOR for documentation purposes.
