Subject: staging: lustre: llite: statahead: remove unneeded null test before free
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=37b5022dd7b9dc0b412e2c2a7d01bd3f32e40db5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: lustre: llite: statahead: remove unneeded null test before free

Kfree can cope with a null argument, so drop null tests.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@ expression ptr; @@

- if (ptr != NULL)
  kfree(ptr);
// </smpl>
