Subject: [PATCH] staging: wilc1000: allocate less memory
Date: Thu, 03 May 2018 10:56:55 +0000	[thread overview]
Message-ID: <20180503105655.GC5315@mwanda> (raw)

We should be allocating space for hidden_network_info structs.  They are
slightly smaller than hidden_network structs.  This bug doesn't cause a
runtime issue beyond the very small ammount of extra memory used.
