Subject: [ATALK]: In notifier handlers convert the void pointer to a netdevice
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=890d52d3f1e28888c4122e120426588f5ad63d37;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[ATALK]: In notifier handlers convert the void pointer to a netdevice

This slightly improves code safety and clarity.

Later network namespace patches touch this code so this is a
preliminary cleanup.
