[PATCH 0/5] update for 3.0.1

[PATCH 0/5] update for 3.0.1

[Wey-Yi Guy]

We do more cleanup works for iwlagn driver

Wey-Yi Guy (5):
  iwlagn: save the latest smps mode
  iwlagn: set smps mode after assoc for 1000 device
  iwlagn: move all post scan functions in one place
  iwlagn: direct call to post_scan function
  iwlagn: call commit_rxon function directly

these patches are also available from wireless-next-2.6 branch on
 git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-2.6.git
