From: Alvin Lee <alvin.l...@amd.com>
commit 8a0f02b7beed7b2b768dbdf3b79960de68f460c5 upstream.
[Why]
There is some logic error where the wrong variable was used to check for
OTG_MASTER and DPP_PIPE.
[How]
Add booleans to confirm that the expected pipes were found before
validating schedulability.

[m.masi...@maxima.ru: In order to adapt this patch to branch 6.1
only changes related to finding the SubVP pipe were applied
as in 6.1 drr_pipe is passed as a function argument.]
