From 70513e1d65599f39aba4fa6594546f7c81fa59f4 Mon Sep 17 00:00:00 2001 From: YueHaibing Date: Tue, 20 Sep 2022 11:21:18 +0800 Subject: [PATCH] crypto: aspeed - Fix check for platform_get_irq() errors The platform_get_irq() function returns negative on error and positive non-zero values on success. It never returns zero, but if it did then treat that as a success. Also remove redundant dev_err() print as platform_get_irq() already prints an error.
