Subject: [ARM] 3295/1: Fix oprofile init return value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7610dfa3723e87705964b29db9775620d96bf618;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[ARM] 3295/1: Fix oprofile init return value

Patch from Russ Dill

The oprofile init code was broken in commit c6b9da. The new logic will
always return -ENODEV. This fixes oprofile_arch_init to return 0 on
success, and return the return value of spec->init() if applicable.
