[PATCH 0/6] staging: wilc1000: don't override user power management selection

[Adham.Abozaeid]

From: Adham Abozaeid <adham.abozaeid@microchip.com>

This patch series has changes to avoid overriding the user's selection
of power management. The current implementation overrides power
management settings according to ip address state, scan state and number
and type of open interfaces.

  staging: wilc1000: remove inetaddr notifier
  staging: wilc1000: remove ip timeout timer
  staging: wilc1000: remove unused members
  staging: wilc1000: avoid overriding powersave state
  staging: wilc1000: apply power management regardless of open
    interfaces
  staging: wilc1000: remove manual sleep mode

[PATCH 1/6] staging: wilc1000: remove inetaddr notifier

[Adham.Abozaeid]

From: Adham Abozaeid <adham.abozaeid@microchip.com>

Driver registers an inetaddr notifier to disable powersave while the ip
address is being obtained which should be controlled only by cfg80211.

The main usage of obtaining_ip was to track the inetadd_notifier status.
After removing the notifier and ip address timeout timer in the first and second patch,
the remaining usage became meaningless, and could be removed.

[PATCH 6/6] staging: wilc1000: remove manual sleep mode

[Adham.Abozaeid]

From: Adham Abozaeid <adham.abozaeid@microchip.com>

manual sleep mode was used to put the wilc1000 chip in sleep while in
disconnected state. This is taken care of in the firmware
