[PATCH 2/3] drivers/net/ethernet/ti/davinci_xxx.c: Move call to PTR_ERR after reassignment

From: Julia Lawall
Date: Thu Feb 02 2012 - 09:01:37 EST


From: Julia Lawall <julia@xxxxxxx>

Delete successive assignments to the same location.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e,e1;
constant c;
@@

*e = c
... when != e = e1
when != &e
when != true IS_ERR(e)
*PTR_ERR(e)
// </smpl>
