[PATCH v4 10/13] USB: ch341: clean up messages

Grigori Goronzy
2016-04-15T21:14:58Z

No functional change. Remove explicit function name printing, it's
easy to use dynamic debug to print it every time, if required.
Fix capitalization and phrasing in some cases. Drop useless
information like a USB buffer pointer, which is not helpful.
