Subject: OMAPDSS: VENC: Replace dssdev->manager with dssdev->output->manager references
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8f1f736c4521ac709d4c5805fa31d395804b162a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

OMAPDSS: VENC: Replace dssdev->manager with dssdev->output->manager references

With addition of output entities, a device connects to an output, and an output
connects to overlay manager. Replace the dssdev->manager references with
dssdev->output->manager to access the manager correctly.

When enabling the VENC output, check whether the output entity connected to
display is not NULL.
