That's a result of a patch from the mid of the series not being applied.
'leds: lm3692x: Allow to configure brigthness mode' introduces that
struct member.

That somehow got lost during merge of this commit:

    https://lore.kernel.org/linux-leds/[email-masked]/T/#u

Pavel, shall i send a patch to fix that up or should we rather try to
get the rest of the series in in the right order? Resetting linux-next
back to cffd61a5c7755546154539dcd7f36590e91e002f for the moment?
