Cover letter [PATCH 5.15 00/30] PCIe Aardvark controller backports for 5.15
Hello Greg, Sasha,
this is backport of all the recet changes for the Aardvark PCIe controller for 5.15.
These include
- memory leak fix in driver unbind
- more complete driver unbind
- fixes for MSI support
- add MSI-X support, which fixes support for some cards
- add ERR interrupt support (which we really missed when debugging)
I also included some small cosmetic changes - this will make it easier to backport next fixes for the driver (there is another batch pending on linux-pci).
