Subject: rt2x00: Fix memleak in tx() path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f3e63a55b1a7b695a79bf3eec2ff5ab6b336037;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

rt2x00: Fix memleak in tx() path

When the tx() handler runs while the device has disapeared,
we did return NETDEV_TX_OK but didn't free the skb.
