Subject: Staging: comedi: usbduxfast: add comedi debug to Kconfig
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0a3b8b642247b509d3308cd9c32156d21505fcb8;p=linux-beck.git

Staging: comedi: usbduxfast: add comedi debug to Kconfig

This patch moves CONFIG_COMEDI_DEBUG to Kconfig and cleans up the code
as it didn't actually compile with debug enabled.
