Subject: [PATCH] usb: dwc3: remove dead code in dwc3_otg_get_irq
Date:   Thu, 23 Mar 2023 13:39:46 +0800

platform_get_irq() only return non-zero irq number on success, or
negative error number on failure.

There is no need to check the return value of platform_get_irq()
to determine the return value of dwc3_otg_get_irq(), removing
them to solve this problem.
