Re: [PATCH 12/11] ARM: OMAP: Fix relative includes for fpga.h

Hi Tony,

After rebasing on top of your omap-for-v3.8/tmp-merge, I realized that this patch is generating a build break due to removal of the fpga.h include from debug-leds.c.

arch/arm/plat-omap/debug-leds.c: In function 'fpga_probe':
arch/arm/plat-omap/debug-leds.c:114:9: error: 'H2P2_DBG_FPGA_SIZE' undeclared (first use in this function)
arch/arm/plat-omap/debug-leds.c:114:9: note: each undeclared identifier is reported only once for each function it appears in

It does not appear with the omap2plus_config but will appear if you enable the NEW_LEDS support that enable OMAP_DEBUG_LEDS.

I'm not sure why the size is still hard coded. In theory, assuming the resource is properly initialized, resource_size should be usable.
The patch below is fixing that.

Regards,
Benoit

Subject: [PATCH] ARM: OMAP: debug-leds: Use resource_size instead of hard coded macro

The debug-leds driver should not rely on hard coded macro for
the iomem size but use the resource size instead.
