[PATCH 0/6] Remove redundant spi driver bus initialization

[PATCH 0/6] Remove redundant spi driver bus initialization

[Antonio Borneo]

This cleanup was already completed between end 2011 and early 2012
with a patch series from Lars-Peter Clausen:
https://lkml.org/lkml/2011/11/24/190

Later on new redundant initialization re-appeared here and there.
Time to cleanup again.

And, yes, I'm lazy! I copy-paste the exact same commit message from
Lars-Peter; only minor reformat to stay in 75 char/line and fix the
name of spi_register_driver().

Regards,
Antonio

[PATCH 4/6] net: ieee802154: Remove redundant spi driver bus initialization

[Antonio Borneo]

In ancient times it was necessary to manually initialize the bus
field of an spi_driver to spi_bus_type. These days this is done in
spi_register_driver(), so we can drop the manual assignment.

Marcel,

I don't see this patch in any linux-next, net-next, bluetooth-next tree.
Could you please apply this patch with the acks by Alan and Varka?
