Subject: [PATCH 28/33] dmaengine: at_hdmac: Use devm_request_irq()
Date: Sat, 20 Aug 2022 15:57:12 +0300 [thread overview]
Message-ID: <20220820125717.588722-29-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20220820125717.588722-1-tudor.ambarus@microchip.com>
IRQs requested with this function will be automatically freed on driver
detach. Use devm_request_irq() and make the code cleaner.
