| |
From: kbuild test robot <fengguang.wu@intel.com>
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.
Generated by: scripts/coccinelle/free/ifnullfree.cocci
Fixes: 0099cc17a399 ("ASoC:topology:avoid error log and oops during topology free.") Signed-off-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Julia Lawall <julia.lawall@lip6.fr> ---
Feel free to ignore this if the null test is useful in some way.
