From fc8d713ecd01acb312afed8c560130ea7284c6db Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 21 Jan 2013 14:02:53 +0100 Subject: drivers/ipack/devices/ipoctal.c: adjust duplicate test Delete successive tests to the same location. The code tested the result of a previous allocation, that itself was already tested. It is changed to test the result of the most recent allocation. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @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 ...; } // Signed-off-by: Julia Lawall Cc: Samuel Iglesias Gonsalvez Signed-off-by: Greg Kroah-Hartman --- drivers/ipack/devices/ipoctal.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/ipack') diff --git a/drivers/ipack/devices/ipoctal.c b/drivers/ipack/devices/ipoctal.c index 93cbf9dda1fe..a2cf0f240929 100644 --- a/drivers/ipack/devices/ipoctal.c +++ b/drivers/ipack/devices/ipoctal.c @@ -289,7 +289,7 @@ static int ipoctal_inst_slot(struct ipoctal *ipoctal, unsigned int bus_nr, ipoctal->mem8_space = devm_ioremap_nocache(&ipoctal->dev->dev, region->start, 0x8000); - if (!addr) { + if (!ipoctal->mem8_space) { dev_err(&ipoctal->dev->dev, "Unable to map slot [%d:%d] MEM8 space!\n", bus_nr, slot); -- cgit v1.2.3-59-g8ed1b
