[PATCH 00/11] update for 3.5: iwlwifi 2012-04-24

[Wey-Yi Guy]

We add reduce tx power feature for bluetooth coex
We also add new module parameter for disable 5GHz band

Emmanuel Grumbach (2):
  iwlwifi: use IWL_* instead of dev_printk when possible
  iwlwifi: don't init trans->reg_lock from the op_mode

Stanislaw Gruszka (1):
  iwlwifi: add option to disable 5GHz band

Wey-Yi Guy (8):
  iwlwifi: remove unused macros
  iwlwifi: add BT reduced tx power flag
  iwlwifi: add checking for the condition to reduce tx power
  iwlwifi: add reduced tx power threshold define
  iwlwifi: small define change
  iwlwifi: send reduce tx power info in command
  iwlwifi: change kill mask based on reduce power state
  iwlwifi: add loose coex lut

these patches are also available from wireless-next branch on
 git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi.git

[PATCH 03/11] iwlwifi: add checking for the condition to reduce tx power

[Wey-Yi Guy]

When bluetooth coex is active and certain condition matched,
driver need to decide should the tx power been reduce or not.
Adding the logic to manage it.

[PATCH 09/11] iwlwifi: use IWL_* instead of dev_printk when possible

[Wey-Yi Guy]

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

Also remove a debug print when allocation error occurred.
The kernel will complain anyway.

[PATCH 10/11] iwlwifi: add option to disable 5GHz band

[Wey-Yi Guy]

From: Stanislaw Gruszka <sgruszka@redhat.com>

There are various problems happened on 5GHz band not observed on
2.4 GHz (microcode errors, queue stuck, etc... ) . Also roaming
between 5GHz AP and 2GHz does not work very well. To workaround
the problems add option to disable 5GHz support. This will help
on environments where APs are dual-band, and devices will not try
to associate on band where issues happen.

This doesn't make any sense. Init it from the transport instead.
