X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ea5a32c00bcacce1d8ac834a70a82f95a1c79425;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

netvsc: remove unnecessary check for NULL hdr

The function init_page_array is always called with a valid pointer
to RNDIS header. No check for NULL is needed.
