Subject: [PATCH 3/4] [v5] wifi: rtw88: remove unused USB bulkout size set
Date:   Thu, 22 Jun 2023 09:44:17 +0300
Message-ID: <20230622064424.38498-3-dmantipov@yandex.ru>

Precedence: bulk

Drop no longer used 'bulkout_size' of 'struct rtw_usb' as well
as related macros from usb.h and leftovers in 'rtw_usb_parse()'.
This follows commit 462c8db6a011 ("wifi: rtw88: usb: drop
now unnecessary URB size check").
