Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into upstream-fixes

Sync with Linus' tree. This is necessary to have a base for
patch that fixes commit 35b4c01e29b ("power_supply: add "powers"
links to self-powered HID devices") which went in through Anton's
tree.
