From 4c3d15358a7ffdd587acc02ec91d28989334d4be Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Wed, 26 Oct 2011 17:27:40 +0100 Subject: [PATCH] staging:iio:kfifo remove entirely pointless code. I really don't want to think about how this bit got in there. It allocates some storage - copies something into it then frees it without making use of it. Oops.
