Masahiro Yamada d92b7a3b52 modpost: deduplicate MODULE_ALIAS() for all drivers
MODULE_DEVICE_TABLE(pnp_card, ...) may have duplicated IDs. For
instance, snd_ad1816a_pnpids[] in sound/isa/ad1816a/ad1816a.c includes
multiple occurrences of the "ADS7180" string within its .devs fields.

Currently, do_pnp_card_entries() handles deduplication on its own, but
this logic should be moved to a common helper function, as drivers in
other subsystems might also have similar duplication issues.

For example, drivers/media/i2c/s5c73m3/s5c73m3.mod.c contains duplicated
MODULE_ALIAS() entries because both s5c73m3-core.c and s5c73m3-spi.c
define the same compatible string.

This commit eliminates redundant MODULE_ALIAS() entries across all
drivers.

[Before]

  $ grep MODULE_ALIAS drivers/media/i2c/s5c73m3/s5c73m3.mod.c
  MODULE_ALIAS("i2c:S5C73M3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3C*");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3C*");

[After]

  $ grep MODULE_ALIAS drivers/media/i2c/s5c73m3/s5c73m3.mod.c
  MODULE_ALIAS("i2c:S5C73M3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3");
  MODULE_ALIAS("of:N*T*Csamsung,s5c73m3C*");

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
