Subject: pkt_sched: use ns_to_ktime() helper
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=46baac38ef633b08168d27df7b02eb14578fb760;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

pkt_sched: use ns_to_ktime() helper

ns_to_ktime() seems better than ktime_set() + ktime_add_ns()
