Subject: [PATCH v1 01/11] pinctrl: aw9523: Destroy mutex on ->remove()
Date: Thu, 14 Mar 2024 01:52:04 +0200	[thread overview]
Message-ID: <20240313235422.180075-2-andy.shevchenko@gmail.com> (raw)
In-Reply-To: <20240313235422.180075-1-andy.shevchenko@gmail.com>

If aw9523_hw_init() fails on ->remove() the mutex left alive.
Destroy it in that case as well. While at it, remove never
true check at the beginning of the function.
