[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. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
