Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/net/ethernet/sfc/ptp.c:2191:35: error: 'efx_copy_channel' undeclared here (not in a function); did you mean 'efx_ptp_channel'?
2191 | .copy = efx_copy_channel,
| ^~~~~~~~~~~~~~~~
| efx_ptp_channel

Caused by commit

54fccfdd7c66 ("sfc: efx_default_channel_type APIs can be static")

interacting with commit

49e6123c65da ("net: sfc: fix memory leak due to ptp channel")

from the net tree.

I have added the following merge fix patch.

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Tue, 10 May 2022 12:56:18 +1000
Subject: [PATCH] fix up for "net: sfc: fix memory leak due to ptp channel"

This is a partial revert of

54fccfdd7c66 ("sfc: efx_default_channel_type APIs can be static")
