[PATCH 26/29] staging: wilc1000: avoid deferred handling of cfg80211 disconnect callback

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

 



From: Ajay Singh <ajay.kathat@xxxxxxxxxxxxx>

Refactor disconnect operation callback to handle from the cfg80211
context. The reason code is not required to pass as parameter to the
function, so remove it.
