From 0cdf4fefadfeeed9a798935cc6a80e57ffb57f89 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Tue, 21 May 2024 12:52:42 +0200 Subject: [PATCH] spi: stm32: Don't warn about spurious interrupts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BugLink: https://bugs.launchpad.net/bugs/2073603 [ Upstream commit 95d7c452a26564ef0c427f2806761b857106d8c4 ] The dev_warn to notify about a spurious interrupt was introduced with the reasoning that these are unexpected. However spurious interrupts tend to trigger continously and the error message on the serial console prevents that the core's detection of spurious interrupts kicks in (which disables the irq) and just floods the console.
