From 758505199e89de48374ed1c8618f95c218e9cd6f Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 20 Oct 2014 11:34:26 -0700 Subject: [PATCH] staging: comedi: addi_apci_3120: tidy up timer subdevice init It appears that this subdevice is actually broken. The subdevice functions all violate the comedi API and, it they did work, it appears they would break the analog input async commands. For now just tidy up the subdevice init. Add the SDF_READABLE subdev_flag, this subdevice provides an (*insn_read). Fix the subdevice 'maxdata' initialization. The timer is 24-bits. Remove the 'len_chanlist' initialization. This member is only used by subdevices that support async commands. Also remove the 'range_table' initialization. The core will set it to range_unknown which is appropriate.
