Commit ce4f6f0c35 ("mwifiex: add platform specific wakeup interrupt
support") added WoWLAN feature only for sdio. This patch moves that
code to the common module so that all the interface drivers can use
it for free. It enables pcie and sdio for its use currently.

Introduce function mwifiex_probe_of() to parse common properties.
Interface drivers get to decide whether or not the device tree node
was a valid one (depending on the compatible property),
Lets fill "adapter->dt_node" in mwifiex_add_card().
The function mwifiex_probe_of() is currently only a place holder with
the next patch adding content to it.

Today all the interface drivers (usb/pcie/sdio) assign the
adapter->dev in the register_dev() callback, although they
have this piece of info well before hand.
This patch makes the device structure available for mwifiex
right at the beginning, so that it can be used for early
initialization if needed.
This is needed for subsequent patches in this patchset that
intend to unify and consolidate some of the code that would
otherwise have to be duplicated among the interface drivers
(sdio, pcie, usb).

The cleanup_if() callback is the inverse of init_if(). We allocate our
'card' interface structure in the probe() function, but we free it in
cleanup_if(). That gives a few problems:
(a) we leak this memory if probe() fails before we reach init_if()
(b) we can't safely utilize 'card' after cleanup_if() -- namely, in
remove() or suspend(), both of which might race with the cleanup
paths in our asynchronous FW initialization path
Solution: just use devm_kzalloc(), which will free this structure
properly when the device is removed -- and drop the set_drvdata(...,
NULL), since the driver core does this for us. This also removes the
temptation to use drvdata == NULL as a hack for checking if the device
has been "cleaned up."
I *do* leave the set_drvdata(..., NULL) for the hacky SDIO
mwifiex_recreate_adapter(), since the device core won't be able to clear
that one for us.

It is observed that if single tid 6 packet comes among with massive tid 0
packets, tid 6 packet may stay in it's queue and will never be
transmited. This is because wmm.highest_queued_prio will be set to 2
during transmission of tid 0 packets As a result, main work thread
keeps on looping without serving that packet. In this case, if command

Following is mwifiex driver-firmware host sleep handshake.
It involves three threads. suspend handler, interrupt handler, interrupt
processing in main work queue.
1) Enter suspend handler
2) Download HS_CFG command
3) Response from firmware for HS_CFG
4) Suspend thread waits until handshake completes(i.e hs_activate becomes
true)
5) SLEEP from firmware
6) SLEEP confirm downloaded to firmware.
7) SLEEP confirm response from firmware
8) Driver processes SLEEP confirm response and set hs_activate to wake up
suspend thread
9) Exit suspend handler
10) Read sleep cookie in loop and wait until it indicates firmware is
sleep.
11) After processing SLEEP confirm response, we are at the end of interrupt
processing routine. Recheck if there are interrupts received while we were
processing them.
During suspend-resume stress test, it's been observed that we may end up
acessing PCIe hardware(in 10 and 11) when PCIe bus is closed which leads
to a kernel crash.
This patch solves the problem with below changes.
a) action 10 above can be done before 8
b) Skip 11 if hs_activated is true. SLEEP confirm response
is the last interrupt from firmware. No need to recheck for
pending interrupts.
c) Add flush_workqueue() in suspend handler.

With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.
Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.

Indeed, mwifiex_create_custom_regdomain() returns NULL in the

Moreover, some other error paths in this function return ERR_PTR

used.
Fix by freeing regd in the error path, and only update
