First round of fixes for IIO in the 4.0 cycle. Note a followup
set dependent on patches in the recent merge windows will follow shortly.

* dht11 - fix a read off the end of an array, add some locking to prevent
          the read function being interrupted and make sure gpio/irq lines
	  are not enabled for irqs during output.
* iadc - timeout should be in jiffies not msecs
* mpu6050 - avoid a null id from ACPI emumeration being dereferenced.
* mxs-lradc - fix up some interaction issues between the touchscreen driver
              and iio driver.  Mostly about making sure that the adc driver
              only affects channels that are not being used for the
              touchscreen.
* ad2s1200 - sign extension fix for a result of c type promotion.
* adis16400 - sign extension fix for a result of c type promotion.
* mcp3422 - scale table was transposed.
* ad5686 - use _optional regulator get to avoid a dummy reg being allocate
           which would cause the driver to fail to initialize.
* gp2ap020a00f - select REGMAP_I2C
* si7020 - revert an incorrect cleanup up and then fix the issue that made
           that cleanup seem like a good idea.
