From: Julia Lawall <julia@xxxxxxx> Delete successive assignments to the same location. In the first case, the hscx array has two elements, so change the assignment to initialize the second one. In the second case, the two assignments are simply identical. Furthermore, neither is necessary, because the effect of the assignment is only visible in the next line, in the assignment in the if test. The patch inlines the right hand side value in the latter assignment and pulls that assignment out of the if test. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression i; @@ *i = ...; i = ...; // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- In the first case, the patch changes the semantics and has not been tested. drivers/isdn/hardware/mISDN/mISDNinfineon.c | 2 +- drivers/isdn/hisax/l3_1tr6.c | 6 ++---- 2 files changed, 3 insertions(+), 5 deletions(-) diff --git a/drivers/isdn/hardware/mISDN/mISDNinfineon.c b/drivers/isdn/hardware/mISDN/mISDNinfineon.c index af25e1f..e90db88 100644 --- a/drivers/isdn/hardware/mISDN/mISDNinfineon.c +++ b/drivers/isdn/hardware/mISDN/mISDNinfineon.c @@ -563,7 +563,7 @@ reset_inf(struct inf_hw *hw) mdelay(10); hw->ipac.isac.adf2 = 0x87; hw->ipac.hscx[0].slot = 0x1f; - hw->ipac.hscx[0].slot = 0x23; + hw->ipac.hscx[1].slot = 0x23; break; case INF_GAZEL_R753: val = inl((u32)hw->cfg.start + GAZEL_CNTRL); diff --git a/drivers/isdn/hisax/l3_1tr6.c b/drivers/isdn/hisax/l3_1tr6.c index b0554f8..ee4dae1 100644 --- a/drivers/isdn/hisax/l3_1tr6.c +++ b/drivers/isdn/hisax/l3_1tr6.c @@ -164,11 +164,9 @@ l3_1tr6_setup(struct l3_process *pc, u_char pr, void *arg) char tmp[80]; struct sk_buff *skb = arg; - p = skb->data; - /* Channel Identification */ - p = skb->data; - if ((p = findie(p, skb->len, WE0_chanID, 0))) { + p = findie(skb->data, skb->len, WE0_chanID, 0); + if (p) { if (p[1] != 1) { l3_1tr6_error(pc, "setup wrong chanID len", skb); return; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
