Pull char/misc driver patches from Greg Kroah-Hartman:
 "Here's the big char/misc driver patches for 3.9-rc1.

  Nothing major here, just lots of different driver updates (mei,
  hyperv, ipack, extcon, vmci, etc.).

  All of these have been in the linux-next tree for a while."

precision (which would also reduce the conversion time).
The module parameter strong_pullup can be set to 0 to disable the
strong pullup or 1 to enable. If enabled the 5V strong pullup will be
enabled when the conversion is taking place provided the master driver
must support the strong pullup (or it falls back to a pullup
strong pullup, 1 to enable autodetection or 2 to force strong pullup.
In case of autodetection, the driver will use the "READ POWER SUPPLY"
command to check if there are pariste powered devices on the bus.
If so, it will activate the master's strong pullup.
In case the detection of parasite devices using this command fails
(seems to be the case with some DS18S20) the strong pullup can
be force-enabled.
If the strong pullup is enabled, the master's strong pullup will be
driven when the conversion is taking place, provided the master driver
does support the strong pullup (or it falls back to a pullup
resistor). The DS18b20 temperature sensor specification lists a
maximum current draw of 1.5mA and that a 5k pullup resistor is not
sufficient. The strong pullup is designed to provide the additional
