From d324fa8021692c54bb9c527e374e1a3cb831cc81 Mon Sep 17 00:00:00 2001 From: Xie He Date: Thu, 10 Sep 2020 23:35:03 -0700 Subject: [PATCH] drivers/net/wan/x25_asy: Remove an unused flag "SLF_OUTWAIT" 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. Signed-off-by: Xie He Signed-off-by: David S.
