The workaround of pretending R1B non-data transfers are data transfers in order for the busy timeout to be respected by the host controller driver is removed. It wasn't useful in a long time. Initially the workaround ensured that R1B commands did not time out by setting the data timeout to be the command timeout in commitcb87ea28ed("mmc: core: Add mmc CMD+ACMD passthrough ioctl"). This was moved inside an if-clause with idata->buf_bytes being set in commit4d6144de8b("mmc: core: check for zero length ioctl data"). Since the workaround is now inside the idata->buf_bytes clause and intended to fix R1B non-data transfers, that do not have buf_bytes set, we can remove the workaround altogether. This was dead code, since data transfers doesn't use R1B commands.

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.
