Subject: [PATCH v4 3/5] staging: r8188eu: incorrect type in csum_ipv6_magic
Date: Mon, 23 Aug 2021 22:30:28 +0530	[thread overview]
Message-ID: <392082864befe91bb03d16ff7ca5e57ba2a8e549.1629563318.git.aakashhemadri123@gmail.com> (raw)
In-Reply-To: <cover.1629563318.git.aakashhemadri123@gmail.com>

Fix sparse warning:
> rtw_br_ext.c:771:84:    got restricted __be16 [usertype] payload_len
> rtw_br_ext.c:773:110: warning: incorrect type in argument 2
    (different base types)
> rtw_br_ext.c:773:110:    expected int len
> rtw_br_ext.c:773:110:    got restricted __be16 [usertype] payload_len

csum_ipv6_magic and csum_partial expect int len not __be16, use
be16_to_cpu()
