Subject: [PATCH] wifi: mwl8k: initialize cmd->addr[] properly
Date: Sat, 4 May 2024 14:38:15 +0300	[thread overview]
Message-ID: <b788be9a-15f5-4cca-a3fe-79df4c8ce7b2@moroto.mountain> (raw)

This loop is supposed to copy the mac address to cmd->addr but the
i++ increment is missing so it copies everything to cmd->addr[0] and
only the last address is recorded.

Fixes: 22bedad3ce11 ("net: convert multicast list to list_head")
Signed-off-by: Dan Carpenter <>
From static analysis.  Untested.
