In case of am43xx family 0x3f mask should have been used for example. Instead of trying to handle each family's mask, just use u8 type to store the mux value since the event offsets are aligned to byte offset.

On i.MX6 SoCs with VPU, the hdmi is working thanks to the CCM_CMEOR[mod_en_ov_vpu] bit which makes the video_27m ungated whatever is in CCM_CCGR3[CG8].

Even now the code is correct since btrfs_commit_transaction would handle an aborted transaction but this is more of an implementation detail. So let's be explicit in handling failure in btrfs_update_root. Furthermore btrfs_commit_transaction can also fail and by ignoring it's return value we could have left the in-memory copy of the root item in an inconsistent state.

[Linux-stable-mirror] [PATCH V2 0/2] PCI/portdrv: Fix switch devctrl error report enable

by Dongdong Liu

PATCH 1/2 is to fix switch upstream/downstream port error report. PATCH 2/2 is to make AER device configuration more reasonable. Delete the upstream/downstream port AER configuraion in PATCH 2/2, but if firmware does not enable upstream/downstream port error reporting, it seems current no place to enable them, so PATCH 2/2 need more suggestion. Please see the commit log for more information. Changes from v1: - Rebase on v4.15-rc2. - Modify the change log. - Add PATCH 2/2.

This has particularly bad effects for some platforms, because we don't stop the power-save timer, and if this timer goes off after the PCI controller has suspended the link, Bad Things will happen. Commit 32faa3f0ee50 ("ath10k: add the PCI PM core suspend/resume ops") got some of this right, in that it understood there was a problem on non-WoWLAN firmware. But it forgot the $subject case. Fix this by moving all the PCI driver suspend/resume logic exclusively into the driver PM hooks. This shouldn't affect WoWLAN support much (this just gets executed later on). I would just as well kill the entirety of ath10k_hif_suspend(), as it's not even implemented on the USB or SDIO drivers. I expect that we don't need the callback, except to return "supported" (i.e., 0) or "not supported" (i.e., -EOPNOTSUPP).

[Linux-stable-mirror] Patch "ath10k: fix build errors with !CONFIG_PM" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ath10k: fix build errors with !CONFIG_PM to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: ath10k-fix-build-errors-with-config_pm.patch and it can be found in the queue-4.14 subdirectory.

But now that ath10k_pci_pm_{suspend,resume}() is compiled unconditionally, we should also compile ath10k_pci_{suspend,resume}() unconditionally. And drop the #ifdef around ath10k_pci_hif_{suspend,resume}() too; they are trivial (empty), so we're not saving much space by compiling them out. And the alternatives would be to sprinkle more __maybe_unused, or spread the #ifdef's further.
