Subject: [GIT PULL] libata fixes for v3.13-rc1

Hello, Linus.

libata device removal path was removing parent device node before its
child, which is mostly harmless but triggers warning after recent
sysfs changes.  Rafael's patch fixes the order.

Other than that, minor controller-specific fixes and device ID
additions.

The patches are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata.git for-3.13-fixes
