Before calling tmio_mmc_host_probe(), the caller is required to enable clocks for its device, as to make it accessible when reading/writing registers during probe. Therefore, the responsibility to disable these clocks, in the error path of ->probe() and during ->remove(), is better managed outside tmio_mmc_host_remove(). As a matter of fact, callers of tmio_mmc_host_remove() already expects this to be the behaviour. However, there's a problem with tmio_mmc_host_remove() when the Kconfig option, CONFIG_PM, is set. More precisely, tmio_mmc_host_remove() may then disable the clock via runtime PM, which leads to clock enable/disable imbalance problems, when the caller of tmio_mmc_host_remove() also tries to disable the same clocks. To solve the problem, let's make sure tmio_mmc_host_remove() leaves the device with clocks enabled, but also make sure to disable the IRQs, as we normally do at ->runtime_suspend().

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.
