Subject: iio: light: apds9960: correct ->last_busy count
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8386c27587594899e4b638010fa0187fe068b295;p=linux-beck.git

iio: light: apds9960: correct ->last_busy count

Add missing pm_runtime_mark_last_busy to apds9960_set_power_state
function.

Unless pm_runtime_mark_last_busy is called the
pm_runtime_put_autosuspend may put the device into suspend before the
delay time requested.
