Subject: staging: dwc2: rename dwc2_check_core_status()
X-Git-Tag: v3.14-rc1~13^2~752
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=057715f280f6f242dab649e4923866fd236723d5;p=kernel%2Fkernel-generic.git

staging: dwc2: rename dwc2_check_core_status()

Rename dwc2_check_core_status() to dwc2_is_controller_alive(), and
make it a boolean function. Also change the message when the
controller is dead to say "dead" instead of "disconnected".
