Hi Greg,

Please find the remaining MHI patches for v5.14. This series has the left over
patches from the previous patchset and one new series that was reviewed a
while ago and put on hold for Ack from Kalle Valo for ath11k.

Summary:

1. Added validation for the channel ID read from event ring. If we get events
from an invalid channel, we throw an error message and skip the event.

2. Fixed the MHI wake routines used for the newer modems such as SDX55 and
SDX65 by using no-op routines only for the older modems and then relying on
the default routines provided by MHI stack for newer ones.

3. Added support for processing the events based on the priorities. Earlier
a fixed priority was used for all events.

4. Added a dedicated flag to the MHI client transfer APIs for inbound
buffer allocation by the MHI stack. Since this patch modifies the MHI
client drivers under "net/", Ack has been collected from the netdev
maintainer.

5. Added support for Cinterion MV31-W modem in pci_generic controller:

6. Rearranged the setting of BHI/BHIe offsets for better validation of the
register values read from MMIO

7. Cleanup of the BHI/BHIe pointers by setting them to NULL to prevent access
after power down.

8. Added support for getting the MMIO register length from the controller
drivers. This helps in validation of the read offsets from MMIO registers.
Since this patch touches ath11k, Ack has been collected from Kalle Valo.

9. With the help of above register length, added check for BHI/BHIe offsets.

Thanks,
Mani
