[PATCH 643/961] staging: brcm80211: remove struct osl_info from driver sources

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

 



From: Arend van Spriel <arend@xxxxxxxxxxxx>

The struct osl_info was being used only in attach functions but
previous changes make the entire usage of this structure obsolete.
