Subject: qdisc: meta return ENOMEM on alloc failure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0c4e4020f0145ed84b0ef9e3fb79c4a022e77e47;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

qdisc: meta return ENOMEM on alloc failure

Rather than returning earlier value (EINVAL), return ENOMEM if
kzalloc fails. Found while reviewing to find another EINVAL condition.
