From: Peter Senna Tschudin <[email protected]> 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 <[email protected]> --- drivers/video/mb862xx/mb862xxfbdrv.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/drivers/video/mb862xx/mb862xxfbdrv.c b/drivers/video/mb862xx/mb862xxfbdrv.c index 57d940b..d68e332 100644 --- a/drivers/video/mb862xx/mb862xxfbdrv.c +++ b/drivers/video/mb862xx/mb862xxfbdrv.c @@ -1052,12 +1052,14 @@ static int __devinit mb862xx_pci_probe(struct pci_dev *pdev, break; default: /* should never occur */ + ret = -EIO; goto rel_reg; } par->fb_base = ioremap(par->fb_base_phys, par->mapped_vram); if (par->fb_base == NULL) { dev_err(dev, "Cannot map framebuffer\n"); + ret = -EIO; goto rel_reg; } @@ -1073,11 +1075,13 @@ static int __devinit mb862xx_pci_probe(struct pci_dev *pdev, dev_dbg(dev, "mmio phys 0x%llx 0x%lx\n", (unsigned long long)par->mmio_base_phys, (ulong)par->mmio_len); - if (mb862xx_pci_gdc_init(par)) + ret = mb862xx_pci_gdc_init(par); + if (ret) goto io_unmap; - if (request_irq(par->irq, mb862xx_intr, IRQF_SHARED, - DRV_NAME, (void *)par)) { + ret = request_irq(par->irq, mb862xx_intr, IRQF_SHARED, + DRV_NAME, (void *)par); + if (ret) { dev_err(dev, "Cannot request irq\n"); goto io_unmap; } -- 1.7.11.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
