Subject: [PATCH AUTOSEL 4.14 05/34] mfd: mt6397: Do not call irq_domain_remove if PMIC unsupported
Date: Tue, 12 Feb 2019 21:39:23 -0500 [thread overview]
Message-ID: <20190213023952.21311-5-sashal@kernel.org> (raw)
In-Reply-To: <20190213023952.21311-1-sashal@kernel.org>
From: Nicolas Boichat <drinkcat@chromium.org>
[ Upstream commit a177276aa098aa47a100d51a13eaaef029604b6d ]
If the PMIC ID is unknown, the current code would call
irq_domain_remove and panic, as pmic->irq_domain is only
initialized by mt6397_irq_init.
Return immediately with an error, if the chip ID is unsupported.
