From 4090d43af4a06690f293178edc4dfd277fb40920 Mon Sep 17 00:00:00 2001 From: Sean Wang Date: Sun, 9 Jan 2022 16:33:50 +0800 Subject: mt76: sdio: disable interrupt in mt76s_sdio_irq It is unnecessary to keep the interrupt enabled in mt76s_sdio_irq because the driver is already aware of the interrupt, schedules the mt76s_txrx_worker to handle the corresponding actions, and eventually, the interrupt would be enabled again when mt76s_txrx_worker finishes its work. So we can safely disable the interrupt in mt76s_sdio_irq as soon as possible to increase the CPU productivity by dropping the redundant interrupt triggers. Note that sdio lock acquired/released would be handled in sdio_irq_work at mmc driver so we don't take care in mt76s_sdio_irq at function driver.
