From b864c387e8f16273aad1453d6457d847e29c3d25 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 22 Sep 2010 22:32:56 -0400 Subject: mtd-utils: clean up zlib.h usage a bit Hide zlib's crc32 in compr_zlib.c and mkfs.ubifs/compr.c. jffs2reader.c and mkfs.jffs2.c don't actually use zlib, so punt the include from the file. mkfs.jffs2.c is implicitly using crc32 from zlib.h instead of the local mtd_crc32, so fix the local usage. otherwise we get warnings about undefined crc32 because the file was redirecting the prototype.
