Subject: [PULL 07/14] misc/pca9552: Fix LED status register indexing in pca955x_get_led()
Date: Mon, 20 Sep 2021 10:09:21 +0200	[thread overview]
Message-ID: <20210920080928.1055567-8-clg@kaod.org> (raw)
In-Reply-To: <20210920080928.1055567-1-clg@kaod.org>

From: Andrew Jeffery <andrew@aj.id.au>

There was a bit of a thinko in the state calculation where every odd pin
in was reported in e.g. "pwm0" mode rather than "off". This was the
result of an incorrect bit shift for the 2-bit field representing each
LED state.
