Subject: drm/i915: Fix reference leak in intel_modeset_readout_hw_state.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b06f8b0df73dea39337e394805827491d0b1585c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Fix reference leak in intel_modeset_readout_hw_state.

Unreference the old mode_blob by calling the crtc_destroy_state
helper before zeroing the crtc_state.
