Subject: [PATCH] drm/i915/display: Get bigjoiner config before dsc config
during readout
Currently we get bigjoiner config after the dsc get config, during HW readout.
Since dsc_get_config now uses bigjoiner flags/pipes to compute DSC PPS
parameter pic_width, this results in a state mismatch when Bigjoiner and DSC
are used together.
So call get bigjoiner config before calling dsc get config function.
LGTM.

Thanks for the review, pushed to drm-intel-next.

Ankit
