When loading the WCH driver on IGX platforms the various information is printed to the kernel log using printk. However, because no level is specified in printk statements, the prints appear as warnings even though they are informational. The WCH driver implements some definitions to enable/disable prints and so wrap these informational prints with WCH_DBG so that they are disabled by default.
