[REGRESSION] [PATCH net-next v5 2/2] net: stmmac: use per-queue 64 bit statistics where necessary

[Uwe Kleine-König]

Hello,

this patch became commit 133466c3bbe171f826294161db203f7670bb30c8 and is
part of v6.6-rc1.

On my arm/stm32mp157 based machine using NFS root this commit makes the
following appear in the kernel log:

	INFO: trying to register non-static key.
	The code is fine but needs lockdep annotation, or maybe
	you didn't initialize this object before use?
	turning off the locking correctness validator.

I didn't try understand this problem, it's too close to quitting time
:-)

Best regards
