problem about 'git am --rej'

[yangerkun <yangerkun@huawei.com>]

Hi,

Trying 'git am --rej'(git version 2.25.4) to apply patch eead1c2ea250 
("netlabel: cope with NULL catmap") with linux stable branch 
4.4.y(git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git), 
it seems the patch has been applied with wrong function(should be 
cipso_v4_parsetag_rbm or cipso_v4_parsetag_rng, but 
cipso_v4_parsetag_enum). Does this a bug or a expected result?
