Subject: linux-next: build failure after merge of the net-next tree

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.

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")
