Subject: staging: comedi: pcl818: remove 'sub_ai' from private data
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=89dac49eed7d82d8f9164dcf22f15ad228d43446;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

staging: comedi: pcl818: remove 'sub_ai' from private data

This member of the private data is a duplicate of the comedi_device
'read_subdev' member. Remove the private data member and use the
comedi_device member instead.
