From 5c6e9bf011bca072648017477b0fe36402be1415 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 21 Jan 2013 14:02:46 +0100 Subject: drivers/usb/chipidea/core.c: adjust duplicate test Delete successive tests to the same location. In this case res has already been tested for being NULL, and calling devm_request_and_ioremap will not make it NULL. On the other hand, devm_request_and_ioremap can return NULL on failure. 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: Alexander Shishkin Signed-off-by: Greg Kroah-Hartman --- drivers/usb/chipidea/core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/usb/chipidea') diff --git a/drivers/usb/chipidea/core.c b/drivers/usb/chipidea/core.c index aebf695a9344..57cae1f897b2 100644 --- a/drivers/usb/chipidea/core.c +++ b/drivers/usb/chipidea/core.c @@ -411,7 +411,7 @@ static int ci_hdrc_probe(struct platform_device *pdev) } base = devm_request_and_ioremap(dev, res); - if (!res) { + if (!base) { dev_err(dev, "can't request and ioremap resource\n"); return -ENOMEM; } -- cgit v1.2.3-70-g09d2 From 7b8bc3aad0deabf3bc50cd2fe29bce29be5681fe Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sun, 27 Jan 2013 22:45:05 -0200 Subject: USB: chipidea: ci13xxx_imx: Remove sparse warning Remove the following sparse warning: drivers/usb/chipidea/ci13xxx_imx.h:22:25: error: dubious one-bit signed bitfield drivers/usb/chipidea/ci13xxx_imx.h:22:25: error: dubious one-bit signed bitfield Signed-off-by: Fabio Estevam Signed-off-by: Greg Kroah-Hartman --- drivers/usb/chipidea/ci13xxx_imx.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/usb/chipidea') diff --git a/drivers/usb/chipidea/ci13xxx_imx.h b/drivers/usb/chipidea/ci13xxx_imx.h index 2e88accb3d67..9cd2e910b1ca 100644 --- a/drivers/usb/chipidea/ci13xxx_imx.h +++ b/drivers/usb/chipidea/ci13xxx_imx.h @@ -19,7 +19,7 @@ struct usbmisc_usb_device { struct device *dev; /* usb controller device */ int index; - int disable_oc:1; /* over current detect disabled */ + unsigned int disable_oc:1; /* over current detect disabled */ }; int usbmisc_set_ops(const struct usbmisc_ops *ops); -- cgit v1.2.3-70-g09d2
