could not complete.

There can ever be only one call to nfc_targets_found() after polling
has been engaged. This could be from a target discovered event from
the driver, or from an error handler to notify poll will never complete.

An HCI command can complete either from an HCI response
(with an HCI result) or as a consequence of any other system
error during processing. The completion therefore needs to take
a standard errno code. The HCI response will convert its result
to a standard errno before calling the completion.

Its safe to stop the BTCOEX timers 'period_timer' and
'no_stomp_timer' before disabling BTCOEX. These timers
can call ath9k_hw_btcoex_enable (or) change the BT
stomp type if they seem to be running after we had
called ath9k_hw_btcoex_disable, which is obviously
not correct.

We are doing MCI cleanup eventhough BTCOEX is not enabled
via module parameter. This means we do ath_mci_cleanup
though we skipped calling ath_mci_setup. Yet it does not
causes any issues now as we free the DMA buffer allocated
only when it is allocated during ath_mci_setup.

As soon as the interface brought up, btcoex timer starts running
eventhough the interface is in idle state and WLAN chip is moved
to full sleep mode. There is no point in running btcoex timer when
the wlan interface is in sleep mode and also it might consumes
more power on WLAN idle unassociated state. So lets stop the
btcoex when wlan is idle state.

Noise floor calibration is performed on longcal interval and
the reading will be updated in history buffer. On rare occasions,
the previous noisefloor calibration might not be completed within
the period and trying to load nf reading will be failed. In such

enough time to complete the calibration. This was already taken

There is not core id with 0x4329, but at the same place in the open
source part of the Broadcom SDK is a check for some device with the
chip id of 0x4329. The device with a chip id of 0x4329 is a full mac
