iwlwifi: Execute runtime calibration always
Runtime DC calibration was previously conditional. Remove this
behaviour, as new devices support runtime DC calibration,
while older devices ignore the runtime DC calibration request.
This patch addresses low TX throughput issues seen with the 6205.

ath9k: fix tx locking issues
The commit "ath9k: simplify tx locking" introduced a soft lockup triggered
by mac80211 sending a BAR frame triggered by a driver call to

ath9k_hw: make bluetooth coexistence support optional at compile time
Many systems (e.g. embedded systems) do not have wifi modules connected to
bluetooth modules, so bluetooth coexistence is irrelevant there. With the
addition of MCI support, ath9k picked up quite a bit of extra code that
can be compiled out this way.
This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for
querying the bluetooth coexistence scheme, allowing the compiler to
eliminate code that uses it, with only very little use of #ifdef.
On MIPS this reduces the total size for the modules by about 20k.

This patch addresses a bug in the dma worker code that keeps draining

Bluetooth: invert locking order in connect path
This move some checking code that was in l2cap_sock_connect() to

lock_sock() before hci_dev_lock() to avoid a deadlock scenario.
