netdev_printk/dynamic_netdev_dbg: Directly call printk_emit
A lot of stack is used in recursive printks with %pV. Using multiple levels of %pV (a logging function with %pV that calls another logging function with %pV) can consume more stack than necessary. Avoid excessive stack use by not calling dev_printk from netdev_printk and dynamic_netdev_dbg. Duplicate the logic and form of dev_printk instead. Make __netdev_printk static. Remove EXPORT_SYMBOL(__netdev_printk) Whitespace and brace style neatening. Signed-off-by: Joe Perches <joe@perches.com> Acked-by: David S.
