Subject: [PATCH 2/6] staging: r8188eu: Remove tests of kernel version
Date: Thu, 29 Jul 2021 12:09:26 -0500	[thread overview]
Message-ID: <20210729170930.23171-3-Larry.Finger@lwfinger.net> (raw)
In-Reply-To: <20210729170930.23171-1-Larry.Finger@lwfinger.net>

In the GitHub repository from which this driver was derived, old kernels
had to be supported. Now that the driver is included in the kernel,
this code can be removed as well as all mention of version.h.

Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net>
