From: Stephen Rothwell Date: Wed, 22 Jun 2005 00:15:47 +0000 (-0700) Subject: [PATCH] ppc64 iSeries: remove IoRetry from iSeries_Device_Node X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a2ebaf250fabc5c5644b707dbee44c9e0ec442e9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [PATCH] ppc64 iSeries: remove IoRetry from iSeries_Device_Node The IoRetry member of iSeries_Devide_Node is really only used locally, so remove it and replace it with a local variable.
