Subject: [PATCH v2] mt76: mt7915: fix endianness warnings in mu radiotap
Date: Thu, 15 Jul 2021 04:19:57 +0800	[thread overview]
Message-ID: <b4a1c893d91ab7cfae9765e8e7ec3369220211ad.1626293825.git.ryder.lee@mediatek.com> (raw)

Fix sparse: sparse: restricted __le32 degrades to integer

Fixes: e63fadb87fe1 ("mt76: mt7915: report HE MU radiotap")
Signed-off-by: Ryder Lee <ryder.lee@mediatek.com>

v2 - use le32_get_bits instead of FIELD_GET.

Hi Felix, please help to fold this into the previous commit.
