From 55ab4f641a3bfbdb7c59b80e194c7242234bbb1f Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 5 Feb 2013 17:23:40 -0700 Subject: [PATCH] staging: comedi: comedi_usb: allow comedi usb drivers to pass a 'context' Allow the comedi usb drivers to pass a 'context' from their (*probe) functions to the comedi core's comedi_usb_auto_config(). This 'context' is then passed to comedi_auto_config() and then to the comedi_driver's (*auto_attach).
