Subject: staging: comedi: 8255: use __comedi_request_region()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e9720fd2b8fa65e4449c1d57b114dd4f6cc0a676;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

staging: comedi: 8255: use __comedi_request_region()

Use __comedi_request_region() to request the I/O regions used by
this driver.

Remove the  error message when the request_region() fails,
comedi_request_reqion() will output the error message if necessary.
