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*");
