This patch gets rid of the statically allocated p54usb firmware string, and

iwmc3200wifi: trim down calibration firmware name
The patch trims down iwmc3200wifi calibration firmware name from
iwmc3200wifi-lmac-calib-sdio.bin to iwmc3200wifi-calib-sdio.bin. We can
shorten the firmware name because all calibration is done by LMAC.

"[PATCH 3/4 v2] ar9170: fix LED power state handling" revealed
a bug which can cause a ugly crash.
The delayed worker is canceled before the LED class functions are
unregistered... So, if something manages to update the LEDs
while unregister routine is running the timer could fire _after_ the
module has been unloaded.

This patch contains a few more mostly random fixes for the USB front-end.
1. handle irq command response, instead of printing it to the console.
2. remove fixed FIXME.
(real fix: "ar9170usb: reset device on resume". )
3. some more one-liner.
- get rid of a useless "return;"
- add a few branch prediction hints in hot-paths
etc.

It looks like mac80211 can request the driver to start beaconing with
a beacon interval of zero in some cases (at least for mesh point). This
does not sound correct and something may need to be fixed in
mac80211. However, taken into account the unpleasantness of getting
stuck in an infinite busy loop with rtnl_lock held, let's add a quick
workaround in the driver to avoid the worst symptom while someone more
familiar with the mesh implementation can figure out what should be done
with mac80211 as far as beacon interval configuration is concerned.

I have a TrendNet 652-BRP running OpenWRT + ath9k very well. The only
problem is that the beacon gets stuck maybe once a day. After
Vasanthakumar Thiagarajan's "ath9k: cleanup beacon parameters
configuration" patch, ath9k would nearly re-configure the beacons after it
detected the stuck beacon, and did a reset. But it would fail the
SC_OP_TSF_RESET check in ath_beacon_config_ap. This patch gets the beacon
fully reconfigured after the reset.

The comment (which I remove) says that the translation is done SPI routines.
IMHO this can't work because the SPI driver does not know whether the incomming
bytes are part of the registers/bytes which need to be flipped or part of
packet data which has to remain untouched.
While adding le helpers I also removed spu_write_u32() which has no users.

1- write interrupt to current index in ICT table.
2- dma RX frame.
3- update RX shared data to indicate last write index.
4- send interrupt.
This could lead to RX race, driver could receive RX interrupt
but the shared data changes does not reflect that.
