From c6236c0ce39c809c336ca929f68cf8ad02cf94e0 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 10 Dec 2013 16:31:25 -0700 Subject: [PATCH] staging: comedi: drivers: fix return value of comedi_load_firmware() Some of the callback functions that upload the firmware in the comedi drivers return a positive value indicating the number of bytes sent to the device. Detect this condition and just return '0' to indicate a successful upload.
