This is a note to let you know that I've just added the patch titled
iio: adc: berlin2-adc: Add missing of_node_put() in error path
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 cbd3a0153cd18a2cbef6bf3cf31bb406c3fc9f55 Mon Sep 17 00:00:00 2001 From: Xiongfeng Wang wangxiongfeng2@huawei.com Date: Tue, 29 Nov 2022 10:03:16 +0800 Subject: iio: adc: berlin2-adc: Add missing of_node_put() in error path
of_get_parent() will return a device_node pointer with refcount incremented. We need to use of_node_put() on it when done. Add the missing of_node_put() in the error path of berlin2_adc_probe();
