This patch was originally part of the xhci DbC series going to 7.2-rc1, but I decided last minute to drop it to let it mature for a while. It enables runtime PM for xhci with DbC enabled. Turns out the series going to 7.2-rc1 is flawed without this patch. It introduces a locking issue that this patch resolves. If possible it would be nice to get this included to 7.2-rc1, or if it's too late, then to rc2. It passed the CI test that discovered the locking issue.
