Subject: [PATCH net-next] drivers/net/wan/x25_asy: Remove an unused flag "SLF_OUTWAIT"
Date: Thu, 10 Sep 2020 23:35:03 -0700	[thread overview]
Message-ID: <20200911063503.152765-1-xie.he.0141@gmail.com> (raw)

The "SLF_OUTWAIT" flag defined in x25_asy.h is not actually used.
It is only cleared at one place in x25_asy.c but is never read or set.
So we can remove it.
