Not clear what that comment means ... dev_vdbg() is the same as dev_dbg() *IF* the VERBOSE option is set, and is otherwise a NOP. That is: two levels of debug messaging, for use as needed. As a rule, some Kconfig option will ccflags-$(CONFIG_DEBUG_whatever) += -DDEBUG to enable DEBUG for that subsystem, and the VERBOSE option (see ) is set selectively by hand. - Dave
