From e40f1e9fb342a2e38fae164861a8cff248ceb87b Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Tue, 19 Apr 2011 16:13:23 -0400 Subject: [PATCH] ARM: zImage: simplify decompress_kernel() The return value for decompress_kernel() is no longer used. Furthermore, this was obtained and stored in a variable called output_ptr which is a complete misnomer for what is actually the size of the decompressed kernel image. Let's get rid of it.
