Subject: macvlan: Stop using NLA_PUT*().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ead9a76ceec34df18dc84cb22053253bd5564376;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

macvlan: Stop using NLA_PUT*().

These macros contain a hidden goto, and are thus extremely error
prone and make code hard to audit.
