Merge branch 'net-convert-to-platform-remove-callback-returning-void'

Uwe Kleine-König says:

====================
net*: Convert to platform remove callback returning void

(implicit) v1 of this series can be found at
https://lore.kernel.org/netdev/20231117095922.876489-1-u.kleine-koenig@pengutronix.de.

Changes since then:

 - Dropped patch #1 as Alex objected. Patch #1 (was #2 before) now
   converts ipa to remove_new() and introduces an error message in the
   error path that failed before.
