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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
