Revision 65d70e79cdb96b208c72a30b34525a850ee640cb authored by Linus Torvalds on 18 December 2015, 20:51:52 UTC, committed by Linus Torvalds on 18 December 2015, 20:51:52 UTC 
Merge tag 'hwmon-for-linus-v4.4-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
 
Pull hwmon fixes from Guenter Roeck:

 - Select CONFIG_BITREVERSE for sht15 driver to avoid build failure if
   it is not configured.

 - Force wait for conversion time for the first valid data in tmp102
   driver to avoid reporting erroneous data to the thermal subsystem.
