msm:mdss: Fix the issue with AD resume (cc2176c1) · Commits · e / devices / android_kernel_sony_msm8994

AD is not configured correctly on dual DSI devices during suspend/resume. The AD configuration data from user space are only copied to the master AD configuration structure, and the AD configuration structure attached to the right mixer (slave AD structure) is never filled. So in the resume function, we cannot use the AD configuration data from the slave AD configuration. Use the one from the master structure instead.
