From 2fd84b9b839c3541815733701a06d9df48297a91 Mon Sep 17 00:00:00 2001 From: Zhang Shurong Date: Sat, 22 Jul 2023 23:29:51 +0800 Subject: uio: pruss: fix to check return value of platform_get_irq() in pruss_probe() The platform_get_irq might be failed and return a negative result. So there should have an error handling code. Fixed this by adding an error handling code.
