Subject: [PATCH] staging: vt6656: Fix vnt_tx_usb_header static checker warning
Date: Sun, 24 May 2020 00:12:41 +0100
Message-ID: <9818e564-81f6-a683-caa0-69423fded401@gmail.com> (raw)

drivers/staging/vt6656/rxtx.c:729 vnt_beacon_xmit()
warn: struct type mismatch 'vnt_beacon_buffer vs vnt_tx_usb_header'

Since the only part of vnt_beacon_buffer is used remove and
replace it with vnt_tx_usb_header.

Fixes: 9deca1e3e2b6 ("staging: vt6656: vnt_beacon_xmit use extra_tx_headroom.")
