[PATCH net-next 4/5] net: l2tp: cleanup: remove redundant condition
From: Asbjoern Sloth Toennesen
Date: Fri Nov 04 2016 - 18:51:35 EST
These assignments follow this pattern:
unsigned int foo:1;
struct nlattr *nla = info->attrs[bar];
if (nla)
foo = nla_get_flag(nla); /* expands to: foo = !!nla */
This could be simplified to: if (nla) foo = 1;
but lets just remove the condition and use the macro,
foo = nla_get_flag(nla);
