From: Bryan O'Sullivan Date: Fri, 25 Aug 2006 18:24:29 +0000 (-0700) Subject: IB/ipath: fix handling of kpiobufs X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ba11203a11835737df980ef3dd3bd8325b9cc94e;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git IB/ipath: fix handling of kpiobufs Change comment: no longer imply that user can set ipath_kpiobufs to zero. Actually set ipath_kpiobufs from parameter. Previously only altered per-device ipath_lastport_piobuf, which was over-written in chip init.
