From 70d837075852f1f10178e5d57b852b035ac1ed97 Mon Sep 17 00:00:00 2001 From: "Cho, Yu-Chen" Date: Wed, 18 May 2011 18:40:10 +0800 Subject: [PATCH] staging/keucr: fix keucr msscsi coding style Fix keucr msscsi.c coding style. Remove externs ,and move MS_SCSIIrp to end, because there are not necessary to add extern for MS_SCSIIrp function.
