Commit e579f56 results in a KCQ initialization error for polaris10
cards. Providing the full SET_RESOURCES packet instead of the truncated
version fixes the problem.
I think this patch may have been one of the stabs at fixing the KCQ
suspend/resume errors. I *think* it may no longer be needed if that is
the case.
Sending this mostly as an FYI to get the patch removed from the 4.12-wip
This reverts commit e579f564c333a7eaddf7e12b1b8414410c36e80f.
