Merge commit '371a00448f95adaa612cf1a0b31a11e7093bc706' of 'git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git'

We need the following 2 patches from the 'net-next' tree for the BCMA flash
driver:

371a004 bcma: detect and register NAND flash device
d57ef3a bcma: detect and register serial flash device

and this is why we are merging the net-next tree (presumably persistent)
up to commit '371a004'.
