Subject: [PATCH 1/3] mii-tool: Fix string length
Date: Wed, 21 May 2014 14:09:54 +0200	[thread overview]
Message-ID: <1400674196-31951-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1400674196-31951-1-git-send-email-s.hauer@pengutronix.de>

media_list writes into a static string. Worst case length of this string
is 125 bytes, but the function only allocates 100 bytes. Use 256 bytes which
is long enough for some extensions.
