6.11-stable review patch. If anyone has any objections, please let me know. ------------------ 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 ... ...
