Hi,

I'm sorry I didn't notice this while passing through the patches 
yesterday.

Could you please make this error message plain english instead of piling 
even more kernel C specifics to it? Preferrably, an user seeing a kernel 
error message should not be required to know/understand any C, so don't 
print __func__ nor write function names into any error/warning/info level 
messages.

Also, it should use dev_err() I think (platform_profile_setup() seems to
mix pr_*() & dev_*() prints with no good reason).
