[alsa-devel] [PATCH] ASoC: soc-core: fix ifnullfree.cocci warnings

[Kuninori Morimoto]

Hi

> sound/soc/soc-core.c:643:2-7: WARNING: NULL check before freeing functions like kfree, debugfs_remove, debugfs_remove_recursive or usb_free_urb is not needed. Maybe consider reorganizing relevant code to avoid passing NULL values.
> 
>  NULL check before some freeing functions is not needed.
> 
>  Based on checkpatch warning
>  "kfree(NULL) is safe this check is probably not required"
>  and kfreeaddr.cocci by Julia Lawall.
