[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Breno Leitao <leitao@xxxxxxxxxx>

[ Upstream commit 843a8851e89e2e85db04caaf88d8554818319047 ]

lib/test_blackhole_dev.c sets a variable that is never read, causing
this following building warning:

	lib/test_blackhole_dev.c:32:17: warning: variable 'ethh' set but not used [-Wunused-but-set-variable]

Remove the variable struct ethhdr *ethh, which is unused.

Fixes: 509e56b37cc3 ("blackhole_dev: add a selftest")
