e7027075d0 bcma: fix null pointer in bcma_core_pci_irq_ctl
pc could be null if hosttype != BCMA_HOSTTYPE_PCI.
If we are on a device without a pci core this function is called with
pc = null by b43 and brcmsmac. If the host type is PCI we have a pci
core as well and pc can not be null.

69aaedd3cf bcma: add ext PA workaround for BCM4331 and BCM43431
MacBook Pro models with BCM4331 wireless have been found to have the ext
PA lines disabled after resuming from S3 without external power attach.
This causes them to be unable to transmit. Add a workaround to ensure
that the ext PA lines are enabled on BCM4331. Also extend all handling
of ext PA line muxing to BCM43431 as is done in the Broadcom SDK.

28f3d71761 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull more networking updates from David Miller:
 "Ok, everything from here on out will be bug fixes."

1) One final sync of wireless and bluetooth stuff from John Linville.
   These changes have all been in his tree for more than a week, and
   therefore have had the necessary -next exposure.  John was just away
   on a trip and didn't have a change to send the pull request until a
   day or two ago.

2) Put back some defines in user exposed header file areas that were
   removed during the tokenring purge.  From Stephen Hemminger and Paul
   Gortmaker.

3) A bug fix for UDP hash table allocation got lost in the pile due to
   one of those "you got it..  no I've got it.." situations.  :-)

   From Tim Bird.

4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll
   try to coalesce overlapping frags and crash.  Fix from Eric Dumazet.

5) RCU routing table lookups can race with free_fib_info(), causing
   crashes when we deref the device pointers in the route.  Fix by
   releasing the net device in the RCU callback.  From Yanmin Zhang.

32998cc96a bcma: use fallback sprom if no on chip sprom is available
bcma should check for a fallback sprom every time it can not find a
sprom on the card itself or a normal external sprom mapped into the
memory of the chip. When otp sprom support was introduced it tried to
read out the sprom from the wireless chip also if no otp sprom was
available. This caused a Data bus error in bcma_sprom_get() when
reading out the sprom for the SoC.

This fixes a regression introduced in commit:

58f743ee06 bcma: fix build error on MIPS; implicit pcibios_enable_device
The following is seen during allmodconfig builds for MIPS:

drivers/bcma/driver_pci_host.c:518:2: error: implicit declaration
of function 'pcibios_enable_device' [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[3]: *** [drivers/bcma/driver_pci_host.o] Error 1

Most likey introduced by commit 49dc957715

    "bcma: add PCIe host controller"

Add the header instead of implicitly assuming it will be present.
Sounds like a good idea, but that alone doesn't fix anything.

The real problem is that the Kconfig has settings related to whether
PCI is possible, i.e.

  config BCMA_HOST_PCI_POSSIBLE
        bool
        depends on BCMA && PCI = y
        default y

  config BCMA_HOST_PCI
        bool "Support for BCMA on PCI-host bus"
        depends on BCMA_HOST_PCI_POSSIBLE

...but what is missing is that BCMA_DRIVER_PCI_HOSTMODE doesn't
have any dependencies on the above.  Add one.

Wireless Broadcom chips can have either their SPROM data stored
on either external SPROM or on-chip OTP memory. Both are accessed

Tested with:
BCM43224 OTP and SPROM
BCM4331 SPROM
BCM4313 OTP

This patch is in response to linux-wireless thread [1].
