If this is
https://lore.kernel.org/all/33c61f23-6442-6d9b-492f-dd6e9c64a8c1@quicinc.com/
(and QLT 1872) then add reported-by tag.

Change seems logical, although not really documented (a bit
contradictory information for sdm845), so assuming this was really tested:

It's not, I fired up 8998, added debug prints and ran mybw.

It's not for sdm845, after the last cleanup both BWMONs on that
one got its own driver data struct.
