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. Thanks Mathias Mathias Nyman (1): xhci: dbc: support runtime suspend while DbC is in enabled state .../testing/sysfs-bus-pci-drivers-xhci_hcd | 2 +- drivers/usb/host/xhci-dbgcap.c | 60 ++++++++++++++++++- drivers/usb/host/xhci-dbgcap.h | 3 + 3 files changed, 62 insertions(+), 3 deletions(-) -- 2.43.0
