From 8518a52c4456c697033bf81f0df73c026200ad8e Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 21 Jan 2015 17:22:13 -0700 Subject: [PATCH] staging: comedi: vmk80xx: GPCT_RESET is not an (*insn_config) instruction The data[0] parameter to (*insn_config) functions is the "configuration instruction" that should be handled. These are defined by the enum configuration_ids in comedi.h. This driver is currently checking the data[0] value to be INSN_CONFIG_RESET or GPCT_RESET in order to reset a counter channel. GPCT_RESET is defined as 0x0001 which would match the configuration instruction INSN_CONFIG_DIO_OUTPUT. That doesn't make any sense for a counter. Remove GPCT_RESET from the insn_cmd test.
