Subject: bond_3ad.c avoid possible null deref
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c99a3d2e04c63a795e13c26d6f2982731e1f1ae0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

bond_3ad.c avoid possible null deref

A few lines earlier we assume that best->slave could be either null or non-null so
we should check it here as well.
