From 8d1467a68426c61807c97163459b481ecb714523 Mon Sep 17 00:00:00 2001 From: Fabien Dessenne Date: Wed, 24 Apr 2019 14:38:44 +0200 Subject: [PATCH] spi: stm32: return the get_irq error During probe, return the "get_irq" error value instead of -ENOENT. This allows the driver to be defer probed if needed.
