Subject: liquidio: use fallback for selecting txq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7410191afcaca3a49bb29bfb5e15f81d7b336984;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

liquidio: use fallback for selecting txq

Remove assignment to ndo_select_queue so that fallback is used for
selecting txq.  Also remove the now-useless function that used to be
assigned to ndo_select_queue.
