count is unsigned and cannot be less than 0.
Is this really a powerpc thing ?
This driver is only build with CONFIG_HDPU_FEATURES and a git grep
HDPU_FEATURES returns no Kconfig that defines it :-)
I'm happy to apply such a trivial thing but it's weird isn't it ?
Ok so it looks like some old stuff that got removed a long time ago and
never made it to arch/powerpc.
I'll send a patch to just remove the whole driver, it's stale.
Cheers,
Ben.
