X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=df06bcff819555bf9aca38b2f8263920836fe851;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: hv: change rndis_filter_device_remove() to void return type

rndis_filter_device_remove() always return 0, so change it to void return
type. Also cleaned up the error checking in the caller.
