Subject: netvsc: eliminate unnecessary skb == NULL checks
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ebc1dcf6008e562a8f88a6b1f4a4705f4d4c4fdd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

netvsc: eliminate unnecessary skb == NULL checks

Since there already is a special case goto for control messages (skb == NULL)
in netvsc_send, there is no need for later checks in same code path.
