Hello Sudip Mukherjee,
The patch b5b4a41b3929: "ALSA: echoaudio: remove all snd_printk" from
Nov 3, 2014, leads to the following static checker warning:
sound/pci/echoaudio/echoaudio.c:1908 snd_echo_free()
error: dereferencing freed memory 'chip'
sound/pci/echoaudio/echoaudio.c
1905 /* release chip data */
1906 free_firmware_cache(chip);
1907 kfree(chip);
^^^^^^^^^^^
1908 dev_dbg(chip->card->dev, "Chip freed.\n");
^^^^^^^^^^
We have lots of printks in this function. We could just delete them all
and no one would care. These days you can get the same information from
ftrace.
1909 return 0;
1910 }
regards,
dan carpenter
