Subject: ipv4/fib: don't warn when primary address is missing if in_dev is dead
From: Paolo Abeni <pabeni@xxxxxxxxxx>
[ Upstream commit 391a20333b8393ef2e13014e6e59d192c5594471 ]
After commit fbd40ea0180a ("ipv4: Don't do expensive useless work
during inetdev destroy.") when deleting an interface,
fib_del_ifaddr() can be executed without any primary address
present on the dead interface.
The above is safe, but triggers some "bug: prim == NULL" warnings.
This commit avoids warning if the in_dev is dead
