From 216f39385181d9f3eabde1b566871ca86694f6b3 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Thu, 6 Sep 2012 11:23:56 -0300 Subject: [PATCH] [media] drivers/media/pci/cx25821/cx25821-video-upstream.c: fix error return code 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/) // ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Peter Senna Tschudin Signed-off-by: Mauro Carvalho Chehab --- .../media/pci/cx25821/cx25821-video-upstream.c | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-) diff --git a/drivers/media/pci/cx25821/cx25821-video-upstream.c b/drivers/media/pci/cx25821/cx25821-video-upstream.c index cca643c91707..7fc97110d973 100644 --- a/drivers/media/pci/cx25821/cx25821-video-upstream.c +++ b/drivers/media/pci/cx25821/cx25821-video-upstream.c @@ -757,7 +757,6 @@ int cx25821_vidupstream_init_ch1(struct cx25821_dev *dev, int channel_select, { struct sram_channel *sram_ch; u32 tmp; - int retval = 0; int err = 0; int data_frame_size = 0; int risc_buffer_size = 0; @@ -800,15 +799,19 @@ int cx25821_vidupstream_init_ch1(struct cx25821_dev *dev, int channel_select, dev->_filename = kmemdup(dev->input_filename, str_length + 1, GFP_KERNEL); - if (!dev->_filename) + if (!dev->_filename) { + err = -ENOENT; goto error; + } } else { str_length = strlen(dev->_defaultname); dev->_filename = kmemdup(dev->_defaultname, str_length + 1, GFP_KERNEL); - if (!dev->_filename) + if (!dev->_filename) { + err = -ENOENT; goto error; + } } /* Default if filename is empty string */ @@ -832,7 +835,7 @@ int cx25821_vidupstream_init_ch1(struct cx25821_dev *dev, int channel_select, dev->_line_size = (dev->_pixel_format == PIXEL_FRMT_422) ?
