The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 2a54c8c9ebc2006bf72554afc84ffc67768979a0 Mon Sep 17 00:00:00 2001 From: Rui Miguel Silva Date: Wed, 12 May 2021 23:39:29 +0100 Subject: iio: gyro: fxas21002c: balance runtime power in error path If we fail to read temperature or axis we need to decrement the runtime pm reference count to trigger autosuspend. Add the call to pm_put to do that in case of error.
