From: Kenji Kaneshige Date: Fri, 22 Dec 2006 01:01:04 +0000 (-0800) Subject: pciehp: remove unnecessary php_ctlr X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=48fe39151727db350347e1dba09d71c8ca24207a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git pciehp: remove unnecessary php_ctlr The struct php_ctlr seems to be only for complicating codes. This patch removes struct php_ctlr and related codes.
