From: H Hartley Sweeten Date: Mon, 12 Oct 2015 23:07:07 +0000 (-0700) Subject: staging: comedi: cb_das16_cs: tidy up analog input subdevice init X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=090b82a3a7bfc192d01ff8910485757db65b858f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git staging: comedi: cb_das16_cs: tidy up analog input subdevice init This driver currently code not support async commands. Remove the SDF_CMD_READ subdev_flag and len_chanlist initialization from the subdevice init. For aesthetics, rename the (*insn_read) function.
