X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7f116b5b6c2418e9d9ba2c2ba82cbbad45e36fc5;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git phonet: Stop using NLA_PUT*(). These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S.
