Currently, the ath12k_get_num_hw() helper function takes the device handle
as an argument. Here, the number of hardware is retrieved from the group
handle. Demanding the device handle from the caller is unnecessary since
in some cases the group handle is already available. Additionally, there
is no longer a need for multiple indirections to get the number of
hardware. Therefore, remove this helper function and directly use
ag->num_hw. This change also fixes the below Smatch static checker
warning.
Smatch warning:
ath12k_mac_destroy() error: we previously assumed 'ab' could be null
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1

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.
