[PATCH 21/31] staging: wfx: drop useless structs only used in hif_ind_startup

From: Jerome Pouiller
Date: Mon Sep 07 2020 - 06:23:57 EST


From: Jérôme Pouiller <jerome.pouiller@xxxxxxxxxx>

The structs hif_capabilities, hif_otp_regul_sel_mode_info and
hif_otp_phy_info have no real reasons to exist. Drop them and simplify
access to fields of struct hif_ind_startup.
