[PATCH 3/6] staging: brcm80211: removed sys directory layer from brcmsmac driver

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

 



Based on review comments moved sources from brcm80211/brcmsmac/sys
to its parent directory. The phy directory is kept for maintainance
logistics around phy source code.
