Subject: zsmalloc: remove null check from destroy_handle_cache()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cd10add00c1b31cd664a31108a9b395025def50a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

zsmalloc: remove null check from destroy_handle_cache()

We can pass a NULL cache pointer to kmem_cache_destroy(), because it
NULL-checks its argument now.  Remove redundant test from
destroy_handle_cache().
