Revision 02f9f5e62a9b0a1af2edd4fbd8194c9c5475459b authored by Imre Deak on 12 February 2016, 16:55:17 UTC, committed by Jani Nikula on 22 February 2016, 15:44:38 UTC
The assumption when adding the intel_display_power_is_enabled() checks was that if it returns success the power can't be turned off afterwards during the HW access, which is guaranteed by modeset locks. This isn't always true, so make sure we hold a dedicated reference for the time of the access. While at it also add the missing reference around the HW access in i915_interrupt_info(). v2: - update the commit message mentioning that this also fixes the HW access in the interrupt info debugfs entry (Daniel) Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1455296121-4742-9-git-send-email-imre.deak@intel.com (cherry picked from commit e129649b7a3e1d50d196e159492496777769437e) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
