We set wl->wow_enabled on every suspend(), so we need to clear it
on every resume().
(we can't rely on setting wl->wow_enabled=false in suspend(),
as it being called only when wowlan triggers are configured)

Since mac80211 calls suspend/resume only when wowlan triggers
exist, there is no need to check for triggers existance in the
callbacks as well.
Add a WARN_ON() to verify it.

If our SDIO function has its runtime PM disabled, don't try to
manipulate its runtime PM status at all. This way we can still
power on cards plugged to mmc hosts that are not MMC_CAP_POWER_OFF_CARD.

The firmware, in practice, treats the channels in three separate
blocks, one for each band (bg, a and j).  Instead of using a single
array and doing some magic with indices, split the array in 3 to make
it more readable.

Allow control over rx_streaming interval and operation mode
(always/only on coex) via debugfs.

e.g.

When rx_streaming.interval is non-zero, use automatic rx streaming.
Enable rx streaming on the each rx/tx packet, and disable it
rx_streaming.duration msecs later.

When rx_streaming.always=0 (default), rx streaming is enabled only
when there is a coex operation.

wl12xx supports the "rx streaming" feature:

When in ps mode, and @timeout msecs have been passed since
the last rx/tx, it issues trigger packets (QoS-null/PS-Poll packets,
according to the ac type) in const intervals (in order to reduce
the rx time).

Two functions in ssb are using register_pci_controller() which is
__devinit. The functions ssb_pcicore_init_hostmode() and
ssb_gige_probe() should also be __devinit.

This fixes the following warning:
WARNING: vmlinux.o(.text+0x2727b8): Section mismatch in reference from the function ssb_pcicore_init_hostmode() to the function .devinit.text:register_pci_controller()
The function ssb_pcicore_init_hostmode() references
the function __devinit register_pci_controller().
This is often because ssb_pcicore_init_hostmode lacks a __devinit
annotation or the annotation of register_pci_controller is wrong.

WARNING: vmlinux.o(.text+0x273398): Section mismatch in reference from the function ssb_gige_probe() to the function .devinit.text:register_pci_controller()
The function ssb_gige_probe() references

This is often because ssb_gige_probe lacks a __devinit
