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

iio: adc: aspeed: Fix refcount leak in aspeed_adc_set_trim_data

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 8a2b6b5687984a010ed094b4f436a2f091987758 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin linmq006@gmail.com Date: Mon, 16 May 2022 11:52:02 +0400 Subject: iio: adc: aspeed: Fix refcount leak in aspeed_adc_set_trim_data

of_find_node_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.
