commit efdff533946284ed013f8e062be66e57463304bf
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0W8

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=efdff533946284ed013f8e062be66e57463304bf



--------------------------------

commit 415ba26c upstream.

Sink only devices do not have any source capabilities, so
the driver should not warn about that. Also DRP (Dual Role
Power) capable devices, such as USB Type-C docking stations,
do not return any source capabilities unless they are
plugged to a power supply themselves.
