From aed3f9d498babd9cf4f0656e4a415cd25c725aa3 Mon Sep 17 00:00:00 2001 From: Chase Southwood Date: Sat, 3 May 2014 02:57:01 -0500 Subject: [PATCH] staging: comedi: addi_apci_1564: absorb apci1564_reset() This is the only reset fuction used by this driver. We can remove it from the boardinfo and absorb the code from hwdrv_apci1564.c into the driver.
