[PATCH 2.6.24] iwlwifi: fix rf_kill state inconsistent during suspend and resume

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch fixes the STATUS_RF_KILL_HW state is not cleared problem if the
device goes to suspend when the rf_kill switch is enabled. The bug causes
the driver always thinks the rf_kill switch is enabled (although it is
disabled) after resume.
