Subject: linux-next: manual merge of the char-misc tree with the char-misc.current tree

Hi all,

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

  drivers/misc/fastrpc.c

between commit:

  01b76c32e3f3 ("misc: fastrpc: add checked value for dma_set_mask")

from the char-misc.current tree and commit:

  977e6c8d1d18 ("misc: fastrpc: use correct spinlock variant")

from the char-misc 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.
