In ath12k_dp_rx_peer_frag_setup(), commitea41925538("wifi: ath12k: add primary link for data path operations") checks whether a link is the primary link, and returns directly if it isn't. In ML scenario where we have non-primary links created, this results in leaking the michael_mic info since it is allocated by default but could never be freed for a non-primary link. Note that we can not move the might-sleep allocation after primary link check since there we are in atomic context (due to spin lock). So keep the default allocation, and then free it before return to fix this issue.

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.
