Subject: staging: brcm80211: remove usage of struct osl_info from util sources
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=26bcc1810b7c982ee3a220425c485c2a301abec1;p=deliverable%2Flinux.git

staging: brcm80211: remove usage of struct osl_info from util sources

Most of the util source files do not need the osl_info anymore due
to previous patches so usage of it has been removed.
