From 89ebc27427695bfc1e769f1dd99bd243d332ac7a Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Sun, 13 Mar 2016 19:48:52 -0400 Subject: drivers/tty: make serial/mvebu-uart.c explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/tty/serial/Kconfig:config SERIAL_MVEBU_UART drivers/tty/serial/Kconfig: bool "Marvell EBU 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. 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 the code wasn't using module_init to begin with, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.
