Linus Torvalds e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

Guenter Roeck 61bb53bcbd hwmon: (iio_hwmon) Add support for humidity sensors
The iio subsystem supports humidity sensors, so it makes sense
to support it in the iio-hwmon bridge as well.

Wolfram Sang 2a1ed07718 hwmon: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Jonathan Cameron 51b53dc991 hwmon: Move the IIO client driver for hwmon out of staging
This driver uses channel maps, defined either through device tree
or platform data, to create a hwmon driver which acts as a client
for the underlying IIO device channels.  Thus a general purpose
IIO adc driver can be used to provide hardware monitoring using a subset
of its channels.

--
 The only non move changes here concern the description and changes to the
 dependencies to IIO explicit and hwmon implicit.

 I'm proposing moving this into hwmon on the basis of placing drivers
 based on what they provide rather than what their underlying hardware
 is.
