From: Peter Senna Tschudin <peter.se...@gmail.com> Convert a nonnegative error return code to a negative one, as returned elsewhere in the function.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Peter Senna Tschudin <peter.se...@gmail.com> --- drivers/media/usb/stk1160/stk1160-i2c.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/usb/stk1160/stk1160-i2c.c b/drivers/media/usb/stk1160/stk1160-i2c.c index 176ac93..850cf28 100644 --- a/drivers/media/usb/stk1160/stk1160-i2c.c +++ b/drivers/media/usb/stk1160/stk1160-i2c.c @@ -116,7 +116,7 @@ static int stk1160_i2c_read_reg(struct stk1160 *dev, u8 addr, if (rc < 0) return rc; - stk1160_read_reg(dev, STK1160_SBUSR_RD, value); + rc = stk1160_read_reg(dev, STK1160_SBUSR_RD, value); if (rc < 0) return rc; -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
