Subject: [PATCH v12 06/25] irqchip: Convert all platform MSI users to the new API
Date: Sat, 27 Jan 2024 21:47:34 +0530
Message-Id: <20240127161753.114685-7-apatel@ventanamicro.com>
In-Reply-To: <20240127161753.114685-1-apatel@ventanamicro.com>
References: <20240127161753.114685-1-apatel@ventanamicro.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

From: Thomas Gleixner <tglx@linutronix.de>

Switch all the users of the platform MSI domain over to invoke the new
interfaces which branch to the original platform MSI functions when the
irqdomain associated to the caller device does not yet provide MSI parent
functionality.

No functional change.
