From fc7f47bf1d0a45304809c42405f82eecfc04fd29 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Sun, 18 Oct 2015 18:21:15 -0400 Subject: [PATCH] drivers/tty: make ehv_bytechan.c explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/tty/Kconfig:config PPC_EPAPR_HV_BYTECHAN drivers/tty/Kconfig: bool "ePAPR hypervisor byte channel driver" ...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. 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. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
