This is found by Smatch static checker warning: drivers/net/wireless/realtek/rtw89/mac80211.c:31 rtw89_ops_tx() error: uninitialized symbol 'qsel'. The warning is because 'qsel' isn't filled by rtw89_core_tx_write() due to failed to write. The way to fix it is to avoid kicking off TX DMA, so add 'return' to the failure case.

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.
