X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d0d37254680fb15fdefe03a0986cfc1e22bcbfc4;p=linux.git

drm/i915: Use intel_get_pipe_timings() and intel_mode_from_pipe_config() in intel_crtc_mode_get()

Eliminate the duplicate code for pipe timing readout in
intel_crtc_mode_get() by using the functions we use for the normal state
readout.

v2: Store dotclock in adjusted_mode instead of the final mode
