I have erroneously picked this patch in the MediaTek tree, as I had misread the
changed file, thought that it was mtk-cmdq-helper.c.

This patch also has the wrong recipients, as this should not go through the
MediaTek trees, but through the mailbox one.

Therefore, I dropped this patch from the MediaTek tree - sorry for the confusion.

Angelo
