Subject: [PATCH v3 2/7] staging: r8188eu: introduce new core dir for RTL8188eu driver
Date: Sat, 24 Jul 2021 01:10:50 +0100 [thread overview]
Message-ID: <20210724001055.1613840-3-phil@philpotter.co.uk> (raw)
In-Reply-To: <20210724001055.1613840-1-phil@philpotter.co.uk>
This patchset is split in order to keep the file sizes down. This core
directory is part of the newer/better driver from GitHub modified by
Larry Finger. Import this as the basis for all future work going
forward.
Suggested-by: Larry Finger <Larry.Finger@lwfinger.net>
