ath9k: fix a scheduling while atomic bug in CSA handling
|
|
|
|
|
|
|
|
|
|
Commit "ath9k: prepare for multi-interface CSA support" added a call to
|
|
|
|
|
ieee80211_iterate_active_interfaces in atomic context (beacon tasklet),
|
|
|
|
|
which is crashing.
|
|
|
|
|
Use ieee80211_iterate_active_interfaces_atomic instead.

ath9k_hw: reduce ANI firstep range for older chips
|
|
|
|
|
|
|
|
|
|
Use 0-8 instead of 0-16, which is closer to the old implementation.
|
|
|
|
|
Also drop the overwrite of the firstep_low parameter to improve
|
|
|
|
|
stability.
