Subject: [PATCH] ARM: 5882/1: ARM: Fix uncompress code compile for different defines of flush(void)
Because of the include of the decompress_inflate.c file from
boot/compress/misc.c, there are different flush() defines:
In file included from arch/arm/boot/compressed/misc.c:249:
arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0
Fix this by removing the define of flush() in misc.c for
CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h,
and that is being included unconditionally.
Also use a static inline function instead of define
for mach-mxc and mach-gemini to avoid similar bug
for those platforms.
