Sorry, but please do not define what is not defined anyway.

Hm... you chose the easy way.
My hope was that you would pick up my hint and keep the functionality,
and just convert it to debug_cond() instead.
For example, as is DEBUG_SETUP() would become "active" only when
DEBUG_S3C_UDC_SETUP is defined; see "include/usb/s3c_udc.h". If we
change the plain "#define DEBUG_S3C_UDC_SETUP" into a
"#define DEBUG_S3C_UDC_SETUP 1", then we can replace all use of
DEBUG_SETUP(foo, ...);
by the standard
debug_cond(DEBUG_S3C_UDC_SETUP != 0, foo, ...);
And similar for all the other DEBUG_S3C_* macros in
"include/usb/s3c_udc.h"
That would be much more useful, wouldn't it?
Best regards,
Wolfgang Denk

its complexity often abstract away its essence. - Fred Brooks, Jr.
