The patch is compile-tested only.
Please test and verify actual functionality, if you're serious about
potentially getting this into the kernel.
Hello Jens,

Sadly I don't have the hardware. This upgrade is part of my Linux Kernel
Mentorship Program project. Like other PCI drivers which I have updated, I could
do compile-testing only. Though this patch covers 54 drivers but the actual
change is done only in drivers/ata/libata-core. Since rest of the drivers
make use of the same ata_pci_device_suspend/resume(), it was a chain reaction. I
only had to change variable binding in "struct pci_driver" variable of dependent
drivers.
That's understandable, but you should find at least some hardware (maybe remotely
accessible) to test this on. I'm not going to apply this without some confidence
that it actually works, and compile only testing is a far cry from that. Lots of
code compiles, but fails miserably at runtime.

While it's touching 54 drivers, at least basic coverage of the most popular
choices will give everybody some confidence that it works in general.
Yes, I agree. Actually with previous drivers, I was able to get help from
maintainers and/or supporters for the hardware testing. Is that possible for
this patch?

Thanks
Vaibhav Gupta
