Subject: klist: implement KLIST_INIT() and DEFINE_KLIST()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1da43e4a9ee942c9c967dbe8839476571df0c3ed;p=linux-beck.git

klist: implement KLIST_INIT() and DEFINE_KLIST()

klist is missing static initializers and definition helper.  Add them.
