Looks like my last change to this patch from if defined to ifdef
broke the warning above with an unbalanced bracket..

Thanks Nishant for catching that, updated patch below.

Subject: [PATCH] ARM: Fix low-level decompress debug code for omap

If DEBUG is enabled for decompress code, the system will hang
as the debug UART is not specified. Fix this by adding the
necessary code for omap2plus.

Note that this won't work properly with multi-omap support
compiled in. Also the debug UART used needs to be patched
in if not omap UART3.
