Merge branch 'upstream-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid

Pull HID fixes from Jiri Kosina:
 "The most important one is a purification of Kconfig for CONFIG_HID;
  the inclusion of HID groups and autoloading didn't leave the Kconfig
  in a really consistent state.  Henrik's patch fixes that.  In addition
  to that, there are two small fixes for logitech and magicmouse
  drivers."

* 'upstream-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
  HID: Fix the generic Kconfig options
  HID: magicmouse: Correct report range of major / minor axes
  HID: logitech: don't use stack based dj_report structures
