Currently to get firmware stats, ath11k_mac_op_get_txpower() calls ath11k_fw_stats_request() and ath11k_mac_op_sta_statistics() calls ath11k_mac_get_fw_stats(). Those two helpers are basically doing the same, except for: 1. ath11k_mac_get_fw_stats() verifies ar->state inside itself. 2. ath11k_mac_get_fw_stats() calls ath11k_mac_fw_stats_request() which then calls ath11k_mac_fw_stats_reset() to free pdev/vdev stats whereas only pdev stats are freed by ath11k_fw_stats_request(). 3. ath11k_mac_get_fw_stats() waits for ar->fw_stats_complete and ar->fw_stats_done, whereas ath11k_fw_stats_request() only waits for ar->fw_stats_complete. Change to call ath11k_mac_get_fw_stats() in ath11k_mac_op_get_txpower(). This is valid because: 1. ath11k_mac_op_get_txpower() also has the same request on ar->state. 2. it is harmless to call ath11k_fw_stats_vdevs_free() since ar->fw_stats.vdevs should be empty and there should be no one expecting it at that time. 3. ath11k_mac_op_get_txpower() only needs pdev stats. For pdev stats, ar->fw_stats_done is set to true whenever ar->fw_stats_complete is set to true in ath11k_update_stats_event(). So additional wait on ar->fw_stats_done does not wast any time.

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.
