Arnd Bergmann c89f8d47a1 [media] s5c73m3: remove duplicate module device table
Clang complains about an extraneous definition of the module
device table after the patch to add it was accidentally merged
twice:

../drivers/media/i2c/s5c73m3/s5c73m3-spi.c:40:1: error: redefinition of
      '__mod_of__s5c73m3_spi_ids_device_table'
MODULE_DEVICE_TABLE(of, s5c73m3_spi_ids);
^
../include/linux/module.h:223:27: note: expanded from macro 'MODULE_DEVICE_TABLE'
extern const typeof(name) __mod_##type##__##name##_device_table         \
                          ^
<scratch space>:99:1: note: expanded from here
__mod_of__s5c73m3_spi_ids_device_table

This removes the second definition.

Mauro Carvalho Chehab 203e942d20 [media] s5c73m3-spi: fix compilation breakage when compiled as Module
commit f934a94bb5 ('s5c73m3: Export OF
module alias information') broke compilation when compiled as module:

In file included from drivers/media/i2c/s5c73m3/s5c73m3-spi.c:22:0:
drivers/media/i2c/s5c73m3/s5c73m3-spi.c:40:40: error: expected ')' before ';' token
 MODULE_DEVICE_TABLE(of, s5c73m3_spi_ids;);
                                        ^

Fix it by removing the extra ';'

Javier Martinez Canillas f934a94bb5 [media] s5c73m3: Export OF module alias information
The SPI core always reports the MODALIAS uevent as "spi:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: SPI id table or OF match table).

So drivers needs to export the SPI id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.

But this means that OF-only drivers needs to have both OF and SPI id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same SPI device name for example.

To avoid the above, the SPI core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

Linus Torvalds 75f5db39ff spi: Updates for v4.4
Quite a lot of activity in SPI this cycle, almost all of it in drivers
 with a few minor improvements and tweaks in the core.
 
  - Updates to pxa2xx to support Intel Broxton and multiple chip selects.
  - Support for big endian in the bcm63xx driver.
  - Multiple slave support for the mt8173
  - New driver for the auxiliary SPI controller in bcm2835 SoCs.
  - Support for Layerscale SoCs in the Freescale DSPI driver.

Antonio Borneo 7ac5f8315e [media] s5c73m3: Remove redundant spi driver bus initialization
In ancient times it was necessary to manually initialize the bus
field of an spi_driver to spi_bus_type. These days this is done in
spi_register_driver(), so we can drop the manual assignment.
