Subject: [PATCH AUTOSEL 4.14 094/108] pinctrl: freescale: imx: Fix an error handling path in 'imx_pinctrl_probe()'
Date: Wed, 17 Jun 2020 21:25:46 -0400 [thread overview]
Message-ID: <20200618012600.608744-94-sashal@kernel.org> (raw)
In-Reply-To: <20200618012600.608744-1-sashal@kernel.org>
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
[ Upstream commit 11d8da5cabf7c6c3263ba2cd9c00260395867048 ]
'pinctrl_unregister()' should not be called to undo
'devm_pinctrl_register_and_init()', it is already handled by the framework.
This simplifies the error handling paths of the probe function.
The 'imx_free_resources()' can be removed as well.
Fixes: a51c158bf0f7 ("pinctrl: imx: use radix trees for groups and functions")
