X-Git-Tag: v3.0~9828^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=19be358212af35bd64d449da82279874099a1a85;p=platform%2Fkernel%2Flinux-amlogic.git

Staging: serqt_usb: fix build due to proc tty changes

Just delete the proc tty usage in the driver as it's not needed and will
go away when it switches over to a usb-serial driver.  This fixes the
build error in the driver.
