From 47252054b4a2d5c8382cb1342f5d4eb89dabf95f Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/4] src/topology/parser.c: drop duplicate safe_strtol_base
The safe_strtol_base() function is defined twice since
f547b2e3 ("conf: introduce safe_strtol_base()") and
5fab157a ("topology: do not call strtol directly")
resulting in the following build failure when alsa-utils is built
statically because safe_strtol_base is defined twice.
Fixes: http://autobuild.buildroot.org/results/08d028004090b2a8292f03910cb9bf80a73ac804

Subject: [PATCH 3/4] conf: fix the export of safe_strto* functions from
libasound
Only one library should define the safe_strto function. Export it
correctly and add _snd_ prefix to avoid possible clashes with the other
application code.
Fixes: 47252054 ("src/topology/parser.c: drop duplicate safe_strtol_base")
