From 29afbe5f5afc2f724b8aef2d11fbe6a7ee48997e Mon Sep 17 00:00:00 2001 From: Dongliang Mu Date: Mon, 26 Sep 2022 21:59:21 +0800 Subject: usb: cdns3: remove dead code Smatch reports the following error: drivers/usb/cdns3/cdns3-plat.c:113 cdns3_plat_probe() warn: platform_get_irq() does not return zero From the document, platform_get_irq_byname_optional only returns non-zero value, and negative value on failure. Fix this by removing the zero value checking.
