From ae0e3b8b159499658dabe54753b5d306045928db Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 31 Oct 2012 16:58:25 -0700 Subject: [PATCH] staging: comedi: addi-data: remove 'b_ValidDriver' from the private data This variable is only used in the detach of the addi-data boards to indicate that the attach of the board was successful and that the reset function can be called. We can use the dev->iobase variable to indicate this instead. Once this variable is set the attach always completes.
