Daniel Golle 4354b34f6f generic: 6.6: sync mt7530 DSA driver with upstream
Backport lots upstream changes, many of them fixes, for the mt7530 DSA
driver, similar to how it was done for Linux 6.1 in the previous commit.

The remaining differences compared to the upstream driver are only
the 'slave' -> 'user', 'master' -> 'conduit' language change in DSA
and the rename of 'struct ethtool_eee' to 'struct ethtool_keee' as
well as tree-wide replacement of ethtool_sprintf with ethtool_puts,
all of them do not have any functional impact.

Apart from some minor bug fixes and style improvements the switch
should now behave more conformant when it comes to link-local frames,
and we will again be able to cleanly pick patches from upstream.

Subject: [PATCH 01/30] net: dsa: mt7530: Convert to platform remove callback
returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
