Dan Carpenter c8024234c2 pm2301-charger: Remove unneeded NULL checks
If "pm2" were NULL we would oops printing the error message.
Fortunately, that's not possible so I have removed the NULL checks.

Linus Torvalds 151173e8ce Highlights:
- OpenFirmware/DeviceTree support for the Power Supply core: the core now
   automatically populates supplied_from hierarchy from the device tree.
   With these patches chargers and batteries can now lookup each other
   without the board files support shim. Rhyland Klein at NVIDIA did the
   work;
 
 - New ST-Ericsson ABX500 hwmon driver. The driver is heavily using the
   AB85xx core and depends on some recent changes to it, so that is why the
   driver comes through the battery tree. It has an appropriate ack from
   the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson
   and Hongbo Zhang at Linaro authored the driver;
 
 - Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes
   touch mfd parts, but these were acked by the appropriate MFD maintainer
   (i.e. Samuel Ortiz). Lee Jones at Linaro did most of the work and lead
   the submission process.
 
 Minor changes, but still worth mentioning:
 
 - Battery temperature reporting fix for Nokia N900 phones;
 - Versatile Express poweroff driver moved into drivers/power/reset/.
 - Tree-wise: use devm_kzalloc() where appropriate;
 - Tree-wise: dev_pm_ops cleanups/fixes.

Lars-Peter Clausen 6b170807cd pm2301-charger: Fix suspend/resume
The pm2301-charger driver implements runtime pm and at the same time uses
the legacy pm callbacks for suspend and resume. This does not work since
the I2C core wont look at the legacy pm callbacks if a driver has the 'pm'
field set. This patch fixes it by moving over to dev_pm_ops for
suspend/resume as well.
