SubjectWARNING: CPU: 3 PID: 1 at flush work.isra.47+0x22c/0x248
Date
Hi,
since v5.5-rc1 four equal consecutive traces appeared that seem related to
rockchip sound. As i wasn't sure to whom sent the report just added
everybody from
./scripts/get_maintainer.pl sound/soc/rockchip/rk3399_gru_sound.c
which is the file containg one of the functions in the trace.

By the way, sound works fine. After all traces, there is this message that
could also be related:
[ 0.625354] da7219 8-001a: Using default DAI clk names: da7219-dai-wclk,
da7219-dai-bclk

Regards,
Vicente.
