Somehow I overlooked your last point. Well, the original code had no
semantics - it wasn't working - but I get your point.
Below a patch to print the __func__'s. Note that all pr_debugs are in the
same function. Maybe the function name should be printed in the first
pr_debug only? If desired, I'll send another patch.

Replace printk wrapper - with a syntax error - by pr_debug; keep printing
the __func__'s. (DEBUG is defined 1 when CONFIG_PCMCIA_DEBUG is set)
