While cleaning the ISR of the meson-gx and acking only raised irqs,
the ack of the irq was moved at the very last stage of the function.
This was stable during the initial tests but it triggered issues with
hs200, under specific loads (like booting android). Acking the irqs
after calling the mmc_request_done() causes the problem.
Moving the ack back to the original place solves the issue. Since the
irq is edge triggered, it does not hurt to ack irq even earlier, so
let's do it early in the ISR.
Fixes: 9c5fdb07a2 ("mmc: meson-gx: ack only raised irq")

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.
