commit 63a7cd660246aa36af263b85c33ecc6601bf04be upstream. Some mmc host drivers may need to fixup a card-detection GPIO's config to e.g. enable the GPIO controllers builtin pull-up resistor on devices where the firmware description of the GPIO is broken (e.g. GpioInt with PullNone instead of PullUp in ACPI DSDT). Since this is the exception rather then the rule adding a config parameter to mmc_gpiod_request_cd() seems undesirable, so instead add a new mmc_gpiod_set_cd_config() function. This is simply a wrapper to call gpiod_set_config() on the card-detect GPIO acquired through mmc_gpiod_request_cd().

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.
