Subject: [PATCH] net: xilinx: axienet: Use common error handling code in axienet_mdio_write()

Add a label so that a bit of exception handling can be better reused
at the end of this function implementation.

This issue was detected by using the Coccinelle software.

Hi Markus,

This change seems reasonable to me.  However, I am assuming that as a
non-bug-fix, this is targeted at net-next.  And net-next is currently
closed for the v6.12 merge window.  Please consider reposting this patch
once net-next reopens.  That will occur after v6.12-rc1 has been released.
Which I expect to be about a week from now.

Also, for networking patches please tag non-bug fixes for
net-next (and bug fixes for net, being sure to include a Fixes tag).

	Subject: [PATCH net-next] ...

Please see https://docs.kernel.org/process/maintainer-netdev.html

Please add a blank line here.

Thanks for this positive feedback.

Would you like to categorise my update suggestion as a correction for
a coding style issue?
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/coding-style.rst?h=v6.11#n526

Will a patch resend really be needed for the proposed adjustment?

Can both development branches benefit from this refactoring?

Regards,
Markus
