Clang warns (or errors with CONFIG_WERROR=y):
drivers/mmc/host/sdhci-cadence.c:297:9: error: variable 'hrs37_mode' is uninitialized when used here [-Werror,-Wuninitialized]
297 | writel(hrs37_mode, hrs37_reg);
| ^~~~~~~~~~
drivers/mmc/host/sdhci-cadence.c:291:16: note: initialize the variable 'hrs37_mode' to silence this warning
291 | u32 hrs37_mode;
| ^
| = 0
A previous revision assigned SDHCI_CDNS_HRS37_MODE_MMC_HS200 to
hrs37_mode in a switch statement but the final revision moved to a
simple if statement. Pass that as the value to writel() and
remove hrs37_mode, clearing up the warning.

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 reStructuredText 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.
