net: netdev_kobject_init: annotate with __init (a48d4bb0) · Commits · 戴 / test

netdev_kobject_init() is only being called from __init context, that is, net_dev_init(), so annotate it with __init as well, thus the kernel can take this as a hint that the function is used only during the initialization phase and free up used memory resources after its invocation. Signed-off-by:
