From: Uwe Kleine-König Date: Tue, 21 May 2024 10:52:42 +0000 (+0200) Subject: spi: stm32: Don't warn about spurious interrupts X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=95d7c452a26564ef0c427f2806761b857106d8c4;p=linux.git spi: stm32: Don't warn about spurious interrupts 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.
