There are three thermal stages defined in the PMIC:
stage 1: warning

Registration of a memory region(MR) through FRMR/fastreg(unlike FMR)
needs a connection/qp. With a proxy qp, this dependency on connection
will be removed, but that needs more infrastructure patches, which is a
work in progress.
As an intermediate fix, the get_mr returns EOPNOTSUPP when

Currently dw_hdmi_setup is only run when the dw-hdmi bridge is enabled,
with the mode set last time.
When the bridge is enabled before any mode is set (this may happen when
booting), the mode won't be set at all, some setup steps will be
skipped or fail, and the HDMI output may not work.

The code was being overly pesimistic. Fork needs to guarantee that a
signal sent to multiple processes is logically delivered before

Hi Sebastian,
Thanks for the response.
"I haven't look in detail at this but your new preempt_disable() makes
things unbalanced for the err != 0 case."
This cannot happen. The only possible return values of this function
are -ENOENT or 0.
In the case where we return -ENOENT, we'll go
