Clang warns (or errors with CONFIG_WERROR=y):
drivers/net/wireless/ath/ath12k/mac.c:8060:9: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized]
8060 | return ret;

drivers/net/wireless/ath/ath12k/mac.c:8022:9: note: initialize the variable 'ret' to silence this warning
8022 | int ret, i, j;

| = 0
1 error generated.
Commit 6db6e70a17f6 ("wifi: ath12k: Introduce the container for mac80211
hw") added a completely uninitialized use of ret. Prior to that change,
-ENOMEM was returned to the callers of ath12k_mac_allocate() whenever
ath12k_mac_hw_allocate() failed. Assign that value to ret to make sure
it is always initialized when used and clear 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 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.
