Subject: [PATCH AUTOSEL 4.19 035/671] rtlwifi: rtl8821ae: replace _rtl8821ae_mrate_idx_to_arfr_id with generic version
Date: Thu, 16 Jan 2020 11:44:26 -0500
Message-ID: <20200116165502.8838-35-sashal@kernel.org> (raw)
In-Reply-To: <20200116165502.8838-1-sashal@kernel.org>

From: Colin Ian King <colin.king@canonical.com>

[ Upstream commit c894696188d5c2af1e636e458190e80c53fb893d ]

Function _rtl8821ae_mrate_idx_to_arfr_id is functionally identical to
the generic version rtl_mrate_idx_to_arfr_id, so remove
_rtl8821ae_mrate_idx_to_arfr_id and use the generic one instead.

This also fixes a missing break statement found by CoverityScan in
_rtl8821ae_mrate_idx_to_arfr_id, namely: CID#1167237 ("Missing break
in switch")

Thanks to Joe Perches for spotting this when I submitted an earlier patch.

Fixes: 3c05bedb5fef ("Staging: rtl8812ae: Add Realtek 8821 PCI WIFI driver")
