caa0a99acd ath9k_htc: Fix panic on FW download failure
Use the correct error condition exit in case firmware download
fails for some reason. Not doing so results in a panic:

usb 1-3: ath9k_htc: Transferred FW: ar9271.fw, size: 51280
usb 1-3: ath9k_htc: Firmware - ar9271.fw download failed
usb 1-3: ath9k_htc: Target is unresponsive
Failed to initialize the device
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

0b5ead91cd ath9k_htc: Cleanup device identification
ath.ko is a common module shared between ath5k, ar9170usb, ath9k and ath9k_htc.
Adding driver specific data to the shared structure would impact all the
drivers. Handling USB device recognition for devices specific to ath9k_htc
can be handled within the driver itself.

Also, AR7010 refers to the processor used in both AR9280/AR9287 based
devices. Rename the device enumerations accordingly.

While at it, check properly for the bus type when choosing the EEPROM
base address for UB95.

Add ath_printk and ath_<level> similar to

This allows a more gradual rename of ath_print
to to ath_dbg or perhaps ath_debug.

This basically removes debug.h leaving
only an #define ath_printk ath_dbg
there and moving all the ATH_DBG_<foo>
enums to ath.h

I do not think there's much purpose for struct
ath_common * being passed to the ath_printk
