2020-01-08MAINTAINERS: Remove myself as co-maintainer for qcom-ethqosNiklas Cassel
As I am no longer with Linaro, I no longer have access to documentation for this IP. The Linaro email will start bouncing soon. Vinod is fully capable to maintain this driver by himself, therefore remove myself as co-maintainer for qcom-ethqos. Signed-off-by: Niklas Cassel <niklas.cassel@wdc.com> Signed-off-by: David S.

2020-01-08usb: musb: fix idling for suspend after disconnect interruptTony Lindgren
When disconnected as USB B-device, suspend interrupt should come before diconnect interrupt, because the DP/DM pins are shorter than the VBUS/GND pins on the USB connectors. But we sometimes get a suspend interrupt after disconnect interrupt. In that case we have devctl set to 99 with VBUS still valid and musb_pm_runtime_check_session() wrongly thinks we have an active session. We have no other interrupts after disconnect coming in this case at least with the omap2430 glue. Let's fix the issue by checking the interrupt status again with delayed work for the devctl 99 case. In the suspend after disconnect case the devctl session bit has cleared by then and musb can idle. For a typical USB B-device connect case we just continue with normal interrupts.

2020-01-08btrfs: do not delete mismatched root refsJosef Bacik
btrfs_del_root_ref() will simply WARN_ON() if the ref doesn't match in any way, and then continue to delete the reference. This shouldn't happen, we have these values because there's more to the reference than the original root and the sub root. If any of these checks fail, return -ENOENT.

2020-01-08btrfs: fix invalid removal of root refJosef Bacik
If we have the following sequence of events btrfs sub create A btrfs sub create A/B btrfs sub snap A C mkdir C/foo mv A/B C/foo rm -rf * We will end up with a transaction abort. The reason for this is because we create a root ref for B pointing to A. When we create a snapshot of C we still have B in our tree, but because the root ref points to A and not C we will make it appear to be empty. The problem happens when we move B into C. This removes the root ref for B pointing to A and adds a ref of B pointing to C. When we rmdir C we'll see that we have a ref to our root and remove the root ref, despite not actually matching our reference name. Now btrfs_del_root_ref() allowing this to work is a bug as well, however we know that this inode does not actually point to a root ref in the first place, so we shouldn't be calling btrfs_del_root_ref() in the first place and instead simply look up our dir index for this item and do the rest of the removal.

2020-01-08btrfs: rework arguments of btrfs_unlink_subvolJosef Bacik
btrfs_unlink_subvol takes the name of the dentry and the root objectid based on what kind of inode this is, either a real subvolume link or a empty one that we inherited as a snapshot. We need to fix how we unlink in the case for BTRFS_EMPTY_SUBVOL_DIR_OBJECTID in the future, so rework btrfs_unlink_subvol to just take the dentry and handle getting the right objectid given the type of inode this is. There is no functional change here, simply pushing the work into btrfs_unlink_subvol() proper.

Add support for 7211 USB wake. Disable all possible 7211 USB logic for S2/S5 if USB wake is not enabled. On the 7211, the XHCI wake signal was not connected properly and only goes to the USB1_USB1_CTRL_TP_DIAG1 diagonstic register. The workaround is to have VPU code running that polls for the proper bit in the DIAG register and to wake the system when the bit is asserted.
