* [media] cx25821: Cleanup filename assignment codePeter Senna Tschudin2013-03-181-15/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm pasting the original code and my proposal on the commit message for make it easy to compare the two versions. Line 62 of cx25821-audio-upstream.h contains: char *_defaultAudioName = "/root/audioGOOD.wav"; Original code after replace kmemdup for kstrdup, and after fix return error code: if (dev->input_audiofilename) { dev->_audiofilename = kstrdup(dev->input_audiofilename, GFP_KERNEL); if (!dev->_audiofilename) { err = -ENOMEM; goto error; } /* Default if filename is empty string */ if (strcmp(dev->input_audiofilename, "") == 0) dev->_audiofilename = "/root/audioGOOD.wav"; } else { dev->_audiofilename = kstrdup(_defaultAudioName, GFP_KERNEL); if (!dev->_audiofilename) { err = -ENOMEM; goto error; } } Code proposed in this patch: if ((dev->input_audiofilename) && (strcmp(dev->input_audiofilename, "") != 0)) dev->_audiofilename = kstrdup(dev->input_audiofilename, GFP_KERNEL); else dev->_audiofilename = kstrdup(_defaultAudioName, GFP_KERNEL); if (!dev->_audiofilename) { err = -ENOMEM; goto error; } Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] cx25821: fix error return code and clean upPeter Senna Tschudin2012-11-221-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The function cx25821_sram_channel_setup_upstream_audio always return zero, so the return value is not saved any more. 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.senna@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
