Gupta,

I already have a question :-)

I'm wondering how are you testing this in your SOC_AM33XX board (which
is not ARCH_OMAP3). You probably have ARCH_OMAP3 always selected?

IMO, no need to depend on any ARCH_xxx, just make it depend on the driver
option itself, which already depends on ARCH_OMAP2PLUS (which is the bigger
SoC family).

Care to send a one-patch fix for that, so this *independent* bug can be
taken by Brian? Please add my Reported-by when you do so.
