Subject: staging: iio: cdc: fix improper return value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=91ca1a8c584f55857b1f6ab20a1d3a1ce7a559bb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: iio: cdc: fix improper return value

At the end of function ad7150_write_event_config(), directly returns 0.
As a result, the errors will be ignored by the callers. It may be better
to return variable "ret".
