Subject: [PATCH v3 1/2] driver core: use NUMA_NO_NODE during device_initialize

Don't use (-1) constant for setting initial device node. Instead, use
the generic NUMA_NO_NODE definition to indicate that "no node id
specified".

Use the proper macro instead of hard-coded (-1) value.

These two patches are independent, so I applied this patch only to
pci/sysfs for v5.16, thanks!

I assume Greg will take the drivers/base patch.

I saw both patches in his
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git
driver-core-next

So I guess there is no need for taking it separately, right Greg ?

No problem, I dropped the pci-sysfs.c patch. Thanks for letting me
know!
