Subject: [PATCH 1/3] serial: pxa: make it explicitly non-modular
Date: Mon, 20 Jun 2016 18:55:03 -0400 [thread overview]
Message-ID: <20160620225505.7320-2-paul.gortmaker@windriver.com> (raw)
In-Reply-To: <20160620225505.7320-1-paul.gortmaker@windriver.com>
The Kconfig currently controlling compilation of this code is:
drivers/tty/serial/Kconfig:config SERIAL_PXA
drivers/tty/serial/Kconfig: bool "PXA 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 module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
Also note that MODULE_DEVICE_TABLE and MODULE_ALIAS are both a
no-op for non-modular builds.
We also delete the MODULE_LICENSE tag since that information is
already contained at the top of the file in the comments.
