Pull staging driver updates from Greg KH:
 "Here is the big staging driver pull request for 4.5-rc1.

  Lots of cleanups and fixes here, not as many as some releases, but
  800+ isn't that bad.  Full details in the shortlog.  All of these have
  been in linux-next for a while"

+Description:
+                By default (value '0'), the capture thread checks for the Conversion
+                Ready Flag to being set prior to committing a new value to the sample
+                buffer. This synchronizes the in-chip conversion rate with the
+                in-driver readout rate at the cost of an additional register read.
+
+                Writing '1' will remove the polling for the Conversion Ready Flags to
+                save the additional i2c transaction, which will improve the bandwidth
+                available for reading data. However, samples can be occasionally skipped
+                or repeated, depending on the beat between the capture and conversion
+                rates.

+Description:
