From 8227088cb3c2afb58a45a946d92f6bf93d04d6de Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Mon, 1 May 2023 18:14:41 +0200 Subject: [PATCH] can: at91_can: at91_chip_start(): don't disable IRQs twice In at91_chip_start() first all IRQs are disabled, they do not have to be disabled again at the end of the function before the requested IRQs are enabled. Remove the 2nd disable of all IRQs at the end of the function.
