| |
The Kconfig currently controlling compilation of this code is:
drivers/tty/Kconfig:config LEGACY_PTYS drivers/tty/Kconfig: bool "Legacy (BSD) PTY support"
...and:
drivers/tty/Kconfig:config UNIX98_PTYS drivers/tty/Kconfig: bool "Unix98 PTY support" if EXPERT
combined with this:
obj-$(CONFIG_LEGACY_PTYS) += pty.o obj-$(CONFIG_UNIX98_PTYS) += pty.o
...meaning that it currently is not being built as a module by anyone.
Lets remove the traces of modularity we can so that when reading the driver there is less 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 don't delete the module.h include since other parts of the file are using content from there.
