Subject: use __lookup_hash() in kern_path_parent()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1e0ea0014479f066ba26f937e8740b8902229616;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

use __lookup_hash() in kern_path_parent()

No need to bother with lookup_one_len() here - it's an overkill
