Subject: linux-next: build failure after merge of the leds tree

Hi all,

After merging the leds tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/leds/leds-lm3692x.c: In function 'lm3692x_max_brightness':
drivers/leds/leds-lm3692x.c:355:9: error: 'struct lm3692x_led' has no member named 'brightness_ctrl'
355 | if (led->brightness_ctrl & LM3692X_MAP_MODE_EXP) {
| ^~
drivers/leds/leds-lm3692x.c: In function 'lm3692x_probe_dt':
drivers/leds/leds-lm3692x.c:437:61: error: 'max_cur' undeclared (first use in this function)
437 | ret = fwnode_property_read_u32(child, "led-max-microamp", &max_cur);
| ^~~~~~~

Caused by commit

ef791c4d0ce8 ("leds: lm3692x: Make sure we don't exceed the maximum LED current")

I have used the leds tree from next-20191220 for today.

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/5826b77d42521595e93d01d53475a8881cad1875.1578134779.git.agx@sigxcpu.org/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?

Cheers,

I kept just three patches from the series, and pushed the result.

Could I get the rest of the series, minus the "exponential" stuff, on
top of that?

Sorry for the confusion,

Pavel

No problem, reshuffling stuff turned out to be simpler than expected:

https://lore.kernel.org/linux-leds/[email protected]/T/#mbbbaabea8ebaba1f864d8a4211d9bcac780261aa

If you don't want the exponential mode setting just omit 5/6 and
6/6.
