linux-next: origin tree build failure

Hi all,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

lib/decompress_unlzo.c:53: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'parse_header'
lib/decompress_unlzo.c:90: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'unlzo'

Caused by commit 7dd65feb6c603e13eba501c34c662259ab38e70e ("lib: add
support for LZO-compressed kernels") and commit
cacb246f8db2b9eba89d44a0f0dd4f6ed93bc113 ("Add LZO compression support
for initramfs and old-style initrd").

I can't figure out how that was supposed to build, so I added the
following patch (which is most likely not correct).

Subject: [PATCH] lib: fixup for unlzo build

I then got these:

lib/decompress_unlzo.c: In function 'unlzo':
lib/decompress_unlzo.c:106: error: 'error' undeclared (first use in this function)
lib/decompress_unlzo.c:111: error: implicit declaration of function 'error'

So I just reverted commit
cacb246f8db2b9eba89d44a0f0dd4f6ed93bc113 ("Add LZO compression support
for initramfs and old-style initrd") after removing my fix above.
