Emmanuel Grumbach 705cd4513a iwlagn: store the irq number to iwl_bus just like dev
Since the irq number is just an unsigned int, store it inside iwl_bus
instead of calling the get_irq ops every time it is needed.

Emmanuel Grumbach 4b55b07fc9 iwlagn: warn about nested SYNC commands
Since there is no protection around SYNC host command mechanism, at least WARN
when collision happens between two SYNC host comamnds. I am not sure there is a
real  issue (beyond the HCMD_ACTIVE flag maintenance) with having two SYNC host
commands at the same time, but at least now, we will know about it.

Emmanuel Grumbach 3599d39a85 iwlagn: add get_dev to iwl_bus_ops
Bus specific layer must know how to return the struct device* of the device.
Implement that as a callback of iwl_bus_ops and use that callback instead of
using the priv->pdev pointer which is meant to disappear soon.

Since the struct device * is needed in hot path, iwl_bus holds a pointer to it
instead of calling get_dev all the time.

* the PCI_DEVICE_TABLE

calls to the bus generic code located in the other files.

Eliad Peller b856439b1b mac80211: add cancel_hw_scan() callback
When suspending, __ieee80211_suspend() calls ieee80211_scan_cancel(),
which will only cancel sw scan. In order to cancel hw scan, the
low-level driver has to cancel it in the suspend() callback. however,
this is too late, as a new scan_work will be enqueued (while the driver
is going into suspend).

Add a new cancel_hw_scan() callback, asking the driver to cancel an
active hw scan, and call it in ieee80211_scan_cancel().
