The Kconfig currently controlling compilation of this code is: drivers/tty/hvc/Kconfig:config HVC_CONSOLE drivers/tty/hvc/Kconfig: bool "pSeries Hypervisor Virtual Console 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 explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. We don't replace module.h with init.h since the file already has that. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
