Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "Intel, nouveau, radeon and qxl.

  Mostly for bugs introduced in the merge window, nothing too shocking"

[ And one cirrus fix added later and not mentioned in the pull request..  - Linus ]

  drm/radeon: use gart memory for DMA ring tests
  drm/radeon: fix speaker allocation setup
  drm/radeon: initialize sadb to NULL in the audio code
  drm/i915: fix short vs. long hpd detection
  drm/i915: Don't trust the DP_DETECT bit for eDP ports on CHV
  Revert "drm/radeon/dpm: drop clk/voltage dependency filters for SI"
  Revert "drm/radeon: drop btc_get_max_clock_from_voltage_dependency_table"
