Subject: [GIT PULL] (part2) battery-2.6.git
Hello Linus,
Here is the second part of the battery tree patches. These are left overs
that I didn't have time to review/apply before the merge window opened. I
didn't want to "spoil" the first pull request with these late patches, so
they were not included.
But the stuff is simple enough, so I thought it is worth asking to pull.
In 'part2':
- A small patch for the RX51 OMAP board (Nokia N900 phone), the patch
creates a battery monitor device instance, so that it can be probed. It
was acked by the OMAP maintainer;
- A couple of late bug fixes for the charger-manager: corrects corner
cases for the battery full handling.
Please pull.
Thanks, and merry holidays to you!
