| |
From: Julia Lawall <Julia.Lawall@lip6.fr>
Delete successive tests to the same location. There was a previous test on ret and it has not been updated since then.
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>
--- Perhaps it was intended to test somthing, but I am not sure what.
