From ed2084360d040a39be1ac9101b13c6fb0146f323 Mon Sep 17 00:00:00 2001 From: Krzysztof Adamski Date: Thu, 22 Jan 2015 19:08:58 +0100 Subject: [PATCH] staging: fbtft: fbtft-core mark functions static This fixes sparse warnings like: warning: symbol XXX was not declared. Should it be static? by declaring all local functions static.
