Doing a rm arch/arm/mach-omap2/*.o;make C=1 arch/arm/mach-omap2/
resulted in the following sparse warnings:

FYI, you may like to try:
make C=2 arch/arm/mach-omap2/
instead of the two-step process:

Gee thanks. /me should update my old bash aliases :D
hmm.. minor nit (with codesourcery 2010.09-50 - 4.5.1):
rm arch/arm/mach-omap2/*.o;make C=1 arch/arm/mach-omap2/ 2>Kerr;make C=2
arch/arm/mach-omap2/ 2>Kerr1;diff Kerr Kerr1

Kinda interesting to note that C=2 does'nt list all potential gcc
warnings :( if one wanted a collated list of all warnings, rm .../*.o
helps I guess.
