| |
Dynamic debug recently added a call to __netdev_printk(). However, when CONFIG_NET is not set, we get the following error:
lib/built-in.o: In function `__dynamic_netdev_dbg': (.text+0x9fda): undefined reference to `__netdev_printk'
Fix this by making the call to __netdev_printk() contingent upon CONFIG_NET. We could have fixed this by defining __netdev_printk() to a 'no-op' in the !CONFIG_NET case. However, this is not consistent with how the networking layer uses netdev_printk(). For example, when CONFIG_NET is not set, netdev_printk() does not have a 'no-op' definition defined.
