Subject: [PATCH] [v2] wifi: rtw89: cleanup rtw89_iqk_info and related code
Date:   Thu,  8 Jun 2023 10:45:25 +0300
Message-Id: <20230608074525.29568-1-dmantipov@yandex.ru>
In-Reply-To: <20230606140806.606352-2-dmantipov@yandex.ru>

Precedence: bulk

Drop useless '_iqk_track()' and 'rtw8852a_iqk_track()' (they
just change 'thermal_rek_en' field which is set but unused
and so removed as well) functions, set but unused 'kcount'
field of 'struct rtw89_iqk_info', convert 'thermal' to local
variables where appropriate (it doesn't need to have longer
storage duration because it is actually used for debugging
purposes only), fix typos.
