Subject: usb: musb: core: Handle Babble condition only in HOST mode
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=97b4129e0562c74e6d75ff081e93202c71aecaa3;p=deliverable%2Flinux.git

usb: musb: core: Handle Babble condition only in HOST mode

BABBLE and RESET share the same interrupt. The interrupt
is considered to be RESET if MUSB is in peripheral mode and
as a BABBLE if MUSB is in HOST mode.

Handle babble condition iff MUSB is in HOST mode.
