Subject: iio:buffer: Wrong sized allocation of demux table elements.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=7cdca1784c6e1c9bacf053847676df53eec7b5ea;p=deliverable%2Flinux.git

iio:buffer: Wrong sized allocation of demux table elements.

The size of the allocation is currently set to the size of the pointer
rather than the structure we should actually be allocating.
