Date: Sat, 25 Jun 2016 22:46:51 -0400 From: Paul Gortmaker <paul.gortmaker@...driver.com> To: <linux-kernel@...r.kernel.org> CC: Paul Gortmaker <paul.gortmaker@...driver.com>, Linus Walleij <linus.walleij@...aro.org>, Shawn Guo <shawn.guo@...aro.org>, <linux-gpio@...r.kernel.org> Subject: [PATCH 18/19] pinctrl: imx28: make it explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/pinctrl/freescale/Kconfig:config PINCTRL_IMX28 drivers/pinctrl/freescale/Kconfig: bool ...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 was not in use by this driver, 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.
