[media] cx25821: Cleanup filename assignment code
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;
}
