Subject: [PATCH AUTOSEL 5.5 008/542] pinctrl: baytrail: Allocate IRQ chip dynamic
Date: Fri, 14 Feb 2020 10:40:00 -0500
Message-ID: <20200214154854.6746-8-sashal@kernel.org> (raw)
In-Reply-To: <20200214154854.6746-1-sashal@kernel.org>

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

[ Upstream commit 539d8bde72c22d760013bf81436d6bb94eb67aed ]

Keeping the IRQ chip definition static shares it with multiple instances
of the GPIO chip in the system. This is bad and now we get this warning
from GPIO library:

"detected irqchip that is shared with multiple gpiochips: please fix the driver."

Hence, move the IRQ chip definition from being driver static into the struct
intel_pinctrl. So a unique IRQ chip is used for each GPIO chip instance.

Fixes: 9f573b98ca50 ("pinctrl: baytrail: Update irq chip operations")
Depends-on: ca8a958e2acb ("pinctrl: baytrail: Pass irqchip when adding gpiochip")
