X-Git-Tag: v2.6.39-rc1~469^2~344
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=26bcc1810b7c982ee3a220425c485c2a301abec1;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.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.
