[PATCH -next] staging: comedi: Remove unused variable ‘min_full_scale’

From: Bixuan Cui
Date: Thu May 13 2021 - 08:12:56 EST


Fix the following build warnings:
drivers/comedi/drivers/jr3_pci.c:507:22:
warning: variable ‘min_full_scale’ set but not used

And fix build warnings after removing ‘min_full_scale’:
drivers/comedi/drivers/jr3_pci.c:189:26:
warning: ‘get_min_full_scales’ defined but not used
static struct six_axis_t get_min_full_scales(struct jr3_sensor __iomem *sensor)
