From: Julia Lawall <julia.law...@lip6.fr> Delete successive tests to the same location. Data is the just previously allocated and tested value. Test the result of the allocation made here instead.
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.law...@lip6.fr> --- The previous code could be further simplified by removing the initializations of ret to -ENOMEM, as is absent in this case.
