On the baseline kernel, the reproducer hit the reported slab-use-after-free i= n tasklet_action_common during ath9k_htc probe failure. With this patch, the = same failure path completed without a KASAN report. Both kernels were run in = QEMU with the syzbot config and ath9k firmware extracted from the syzbot root= fs.
