[PATCH AUTOSEL 6.11 51/76] usb: typec: tipd: Free IRQ only if it was requested before

[Sasha Levin]

From: Wadim Egorov <w.egorov@xxxxxxxxx>

[ 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
