Subject: [Stable-8.1.3 20/55] misc/led: LED state is set opposite of what is expected
Date: Thu, 9 Nov 2023 16:42:24 +0300

From: Glenn Miles <milesg@linux.vnet.ibm.com>

Testing of the LED state showed that when the LED polarity was
set to GPIO_POLARITY_ACTIVE_LOW and a low logic value was set on
the input GPIO of the LED, the LED was being turn off when it was
expected to be turned on.
