Subject: r8152: replace netdev_alloc_skb_ip_align with napi_alloc_skb
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c8d83963709ea69f7433c7b4fe3e8c3a4288458a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

r8152: replace netdev_alloc_skb_ip_align with napi_alloc_skb

Replace netdev_alloc_skb_ip_align() with napi_alloc_skb() which can save
several CPU cycles by avoiding having to disable and re-enable IRQs.
