This is a note to let you know that I've just added the patch titled

iio: itg3200: Call iio_trigger_notify_done() on error

to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch.

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: Lars-Peter Clausen lars@metafoo.de Date: Mon, 1 Nov 2021 15:40:54 +0100 Subject: iio: itg3200: Call iio_trigger_notify_done() on error

IIO trigger handlers must call iio_trigger_notify_done() when done. This must be done even when an error occurred. Otherwise the trigger will be seen as busy indefinitely and the trigger handler will never be called again.

The itg3200 driver neglects to call iio_trigger_notify_done() when there is an error reading the gyro data. Fix this by making sure that iio_trigger_notify_done() is included in the error exit path.
