Full build log

Hello,

I cannot build kernel 5.5.6 and after (tested on 5.5.8 and 5.5.11) with LEDS_LM3532.

Build error:
  LD      .tmp_vmlinux1
ld: drivers/leds/leds-lm3532.o: in function `lm3532_probe':
leds-lm3532.c:(.text+0x2d2): undefined reference to `__devm_regmap_init_i2c'
make: *** [Makefile:1078: vmlinux] Error 1

Config is defconfig with CONFIG_LEDS_LM3532 enabled.

Kernel 5.5.5 and before builds ok.

Regards

Patch adding REGMAP_I2C

The problem seems to be resolved when I add "depends on REGMAP_I2C" in the leds Kconfig for LEDS_LM3532.
