OMAP3: RX51: build warning at rx51_t2scripts

[Roger Quadros]

Hi Amit,

I get the following warning while building Kevin's PM branch for RX-51.
The kernel boots to shell though.
I'm not sure whether it's harmless or not.


MODPOST vmlinux.o
WARNING: vmlinux.o(.data+0xb328): Section mismatch in reference from the 
variable rx51_t2scripts_data to the (unknown reference) .init.data:(unknown)
The variable rx51_t2scripts_data references
the (unknown reference) __initdata (unknown)
If the reference is valid then annotate the
variable with __init* (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,

Attached patch should fix this problem. Compile-tested only. 

I've already applied this to the code that I am pushing upstream. So
this should be dropped eventually.

Subject: [PATCH 195/195] TWL4030: RX51: Mark board data as __initdata

Mark rx51 board data as __initdata so that compiling with
CONFIG_DEBUG_SECTION_MISMATCH=y will not throw warnings.
