Subject: [PATCH] video: fbdev: via_aux_vt1636: remove VLA usage
Date: Wed, 7 Mar 2018 13:47:03 -0600	[thread overview]
Message-ID: <20180307194703.GA3862@embeddedgus> (raw)

In preparation to enabling -Wvla, remove VLA and replace it
with a fixed-length array instead. Also, remove variable 'len'.

Notice that no new IDs have been added in seven years.
