Subject: [PATCH 3.12 17/88] macintosh/therm_windtunnel: Export I2C module alias information

From: Javier Martinez Canillas <javier@....samsung.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit cb0eefcc3271ea1d370476dd29685918b99c5a9f upstream.

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So the driver needs to export the I2C table and this
be built into the module or udev won't have the necessary information
to auto load the correct module when the device is added.
