From: H Hartley Sweeten Date: Tue, 5 Mar 2013 17:23:10 +0000 (-0700) Subject: staging: comedi: addi_common: allow driver to set the board_ptr X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1f388811b54f9f1b78d52237edda1eaea109e900;p=linux-beck.git staging: comedi: addi_common: allow driver to set the board_ptr The addi_apci_035, addi_apci_1500, addi_apci_1564, and addi_apci_3xxx drivers still use the addi_common code. Allow those drivers to set the dev->board_ptr before calling addi_auto_attach().
