Subject: linux-next: manual merge of the spi tree with the powerpc tree

Hi all,

Today's linux-next merge of the spi tree got a conflict in:

  drivers/spi/spi-mpc52xx.c

between commit:

  e10656114d32 ("spi: mpc52xx: Avoid using get_tbl()")

from the powerpc tree and commit:

  258ea99fe25a ("spi: spi-mpc52xx: Use new structure for SPI transfer delays")

from the spi tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

BTW Mark: the author's address in 258ea99fe25a uses a non existent domain :-(
