From: Ville Syrjälä Date: Tue, 8 Jan 2019 17:28:27 +0000 (+0200) Subject: drm/radeon: Use drm_hdmi_avi_infoframe_quant_range() X-Git-Tag: v5.15~6857^2~23^2~78 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=8ee491b4d29b48530ed9220059edd2f666bf2889;p=mirror_ubuntu-kernels.git drm/radeon: Use drm_hdmi_avi_infoframe_quant_range() Fill out the AVI infoframe quantization range bits using drm_hdmi_avi_infoframe_quant_range() instead of hand rolling it. This changes the behaviour slightly as drm_hdmi_avi_infoframe_quant_range() will set a non-zero Q bit even when QS==0 iff the Q bit matched the default quantization range for the given mode. This matches the recommendation in HDMI 2.0 and is allowed even before that.
