Re: [alsa-devel] ALSA: echoaudio: remove all snd_printk

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
