X-Git-Tag: v6.11-rc6~34^2~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=32108c22ac619c32dd6db594319e259b63bfb387;p=thirdparty%2Fkernel%2Flinux.git

ALSA: seq: Skip event type filtering for UMP events

UMP events don't use the event type field, hence it's invalid to apply
the filter, which may drop the events unexpectedly.
Skip the event filtering for UMP events, instead.
