The code dealing with busy detection is somewhat complicated. In a way to make it a bit clearer, let's try to clarify the comments in the code about it. Additionally, move the part for clearing the so called busy start IRQ, to the place where the IRQ is actually delivered. Ideally, this should make the code a bit more robust. Finally, to improve understanding of the code and the sequence of the busy detection, move the corresponding code around a bit in mmci_cmd_irq().

README
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.
