drm/dp: Allow signals to interrupt drm_aux-dev reads/writes Let's be nice and interrupt the dpcd aux-dev reads/writes when there's a signal pending. Much nicer if the user can hit ^C instead of having to sit around waiting for the read/write to finish. time dd if=/dev/drm_dp_aux0 bs=$((1024*1024)) ^C before: real 0m34.681s user 0m0.003s sys 0m6.880s after: real 0m0.222s user 0m0.006s sys 0m0.057s Cc: Rafael Antognolli <rafael.antognolli@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1461786225-7790-1-git-send-email-ville.syrjala@linux.intel.com
