Subject: [PATCH v5 5/6] wifi: rtlwifi: Clean up rtl8192d-common a bit
From: Bitterblue Smith <rtl8821cerfe2@gmail.com>

Improve readability:
 * add empty lines
 * use abs_diff in rtl92d_dm_txpower_tracking_callback_thermalmeter
 * roll up repeated statements into a for loop in
   rtl92d_dm_txpower_tracking_callback_thermalmeter
 * shorten lines by replacing many instances of "rtlpriv->dm" with "dm"
   pointer in rtl92d_dm_txpower_tracking_callback_thermalmeter
 * sort some declarations by length
 * refactor _rtl92d_get_txpower_writeval_by_regulatory a little

Delete unused structs tag_dynamic_init_gain_operation_type_definition
and swat.

Simplify rtl92d_fill_h2c_cmd a little and delete a pointless wrapper
function.
