Date: Fri, 11 Feb 2022 19:14:53 +0100 Message-Id: <20220211181500.1856198-1-bigeasy@linutronix.de> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-i2c@vger.kernel.org handler/ interrupt controller entry). It is low level code and the function expects that interrupts are disabled at entry point. This isn't the case for invocations from tasklets, workqueues or the primary interrupt handler on PREEMPT_RT. Once this gets noticed a "local_irq_disable|safe()" is added. To avoid further confusion this series adds generic_handle_irq_safe() which can be used from any context and adds a few user. v2…v4: - Correct kernel doc for generic_handle_irq_safe() as per Wolfram Sang. - Use "misc" instead of "mfd" for the hi6421-spmi-pmic driver. v2…v1: https://lore.kernel.org/all/20220131123404.175438-1-bigeasy@linutronix.de/ - Redo kernel-doc for generic_handle_irq_safe() in #1. - Use generic_handle_irq_safe() instead of generic_handle_irq() in the patch description where I accidently used the wrong one. v1: https://lore.kernel.org/all/20220127113303.3012207-1-bigeasy@linutronix.de/
