Subject: [PATCH v4 5/7] mfd: ezx-pcap: Use generic_handle_irq_safe().
Date: Fri, 11 Feb 2022 19:14:58 +0100	[thread overview]
Message-ID: <20220211181500.1856198-6-bigeasy@linutronix.de> (raw)
In-Reply-To: <20220211181500.1856198-1-bigeasy@linutronix.de>

Instead of manually disabling interrupts before invoking use
generic_handle_irq_safe() which can be invoked with enabled and disabled
interrupts.
