Sounds good to me. Note that the fix depends on
30332eeefec8 ("debugfs: regset32: Add Runtime PM support")
which went into 5.7.
This can be documented as
Cc: stable@xxxxxxxxxxxxxxx # 3.2: 30332eeefec8: debugfs: regset32: Add Runtime PM support
(see Documentation/process/stable-kernel-rules.rst).
Note that this issue appears to have been there since the driver was
first merged in 3.2.
