Subject: [PATCH AUTOSEL 6.6 41/58] usb: typec: tipd: Free IRQ only if it was requested before
Date: Fri, 4 Oct 2024 14:24:14 -0400 [thread overview]
Message-ID: <20241004182503.3672477-41-sashal@kernel.org> (raw)
In-Reply-To: <20241004182503.3672477-1-sashal@kernel.org>
From: Wadim Egorov <w.egorov@phytec.de>
[ Upstream commit db63d9868f7f310de44ba7bea584e2454f8b4ed0 ]
In polling mode, if no IRQ was requested there is no need to free it.
Call devm_free_irq() only if client->irq is set. This fixes the warning
caused by the tps6598x module removal:
WARNING: CPU: 2 PID: 333 at kernel/irq/devres.c:144 devm_free_irq+0x80/0x8c
...
