Subject: arcnet: move dev_free_skb to its only user
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b82de0e28ccac15e1a0c3b4f6f20dfd230049041;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

arcnet: move dev_free_skb to its only user

The call for dev_free_skb is done only once. This patch
moves its call to its only user and removes the obsolete
condition variable.
