From: H Hartley Sweeten Date: Thu, 22 Jan 2015 00:22:13 +0000 (-0700) Subject: staging: comedi: vmk80xx: GPCT_RESET is not an (*insn_config) instruction X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8518a52c4456c697033bf81f0df73c026200ad8e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git 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.
