Subject: iio: Use ktime_get_real_ns()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fb31cc153dec0d4bdd9a5d7ce60d61acd04b4304;p=linux-beck.git

iio: Use ktime_get_real_ns()

No idea why iio needs wall clock based time stamps, but we can avoid
the timespec conversion dance by using the new interfaces.
