The check of ezusb_firmware_download() return value (added by commit
488ec878034eccb852267b0e27ce9d511f75c587) is broken because
ezusb_firmware_download() returns 1 on success.
This causes the driver not to work with the following error:
orinoco_usb: probe of 3-3:1.0 failed with error -14
Check the return value only for negative values.
This fix should be applied to -stable kernels too.

Systems with multiple DFS channel detectors need to track
timestamp of previous pulse per instance to display the
correct pulse interval.
Since the interval value is used for debug printing only,
this is a non-functional modification.

Fix a bug in nvm_read_section function if size of the section
is a multiple of 2K:
- if the size of the section is *not* multiple of 2K,
then we will have: read(2K) - return 2K ... read(2K) - return 2K
read(2K) - return the rest (in bytes) and exit the while loop.
- else, if the size of the section is a multiple of 2K,
then we have: read(2K) - return 2K read(2K) - return 2K read(2K) -
return 2K read(2K) - return 0 and exit the while with an error.
We should not return an error in the latter case, because it
might well be that the section was completely read.

When calling IWL_DEBUG_*() dev_dbg() is currently used, and this
could result in the log being ignored no matter the internal
loglevel, since dev_dbg() may get turned on or off based on the
dynamic debug mechanism.
Replace the dev_dbg() with dev_printk() since dynamic printing
is pointless as we use our own debug level mechanism and there
is just a single dev_dbg() call in the code.

A binding object associates virtual MACs to a Phy.
Binding object can ask (and get) air time, thus
allowing several MACs to share the medium.
A binding object can be in either one of 3 states:
1) standalone - A single active MAC
2) Different Channel Mode (DCM) - There are 2 active
MACs or more (not necessarily just clients), but each
has its own channel.
3) Same Channel Mode (SCM) - There are 2 active
MACs or more (not necessarily just clients), that
share the same channel.
This patch introduces an additional condition for enabling uAPSD:
uAPSD should be disabled for a client in DCM.
The reason for that is a low latency issue in Miracast.

interrupt straight away. This interrupt won't be sent
because it is masked in the hardware.
But if our interrupt service routine is called for another

and service it. This can cause bad things if we are not
