Greg-san,

I am sorry for confusion.
I sent the patch twice since following patch was applied (gregkh/staging-next)

commit 9d36976fad3008fcc4209789566f7f3e7763f212
Modify qt_status_change_check() and delete qt_status_change().

-Incorporate comment of Mr.Joe Perches (sent Nov.17)
-I sent yesterday

Please discard the patches.

Thanks,


YAMANE Toshiaki
