arch/powerpc/platforms/85xx/p1022_ds.c: adjust duplicate test
Delete successive tests to the same location. The code tested the result of a previous call, that itself was already tested. It is changed to test the result of the most recent call. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @s exists@ local idexpression y; expression x,e; @@ *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } ... when != \(y = e\|y += e\|y -= e\|y |= e\|y &= e\|y++\|y--\|&y\) when != \(XT_GETPAGE(...,y)\|WMI_CMD_BUF(...)\) *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
