Created attachment 288027 [details] 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
Created attachment 288029 [details] Patch adding REGMAP_I2C The problem seems to be resolved when I add "depends on REGMAP_I2C" in the leds Kconfig for LEDS_LM3532.
