Subject: OMAPDSS: RFBI: Replace dssdev->manager with dssdev->output->manager references
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1db39c0a28483582c165b4f0ea07ca4a600a4630;p=linux-beck.git

OMAPDSS: RFBI: 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 RFBI output, check whether the output entity connected to
display is not NULL.
