SubjectRe: [PATCH v5 2/2] leds: rt5033: Add RT5033 Flash led device driver
Hi Ingi,

Thanks for the update. I have few comments below.

What is the purpose of this function? It seems to return
a value that is always equal to led->fled_mask, regardless of the
fled_id passed. Just use led->fled_mask directly.

I infer that the purpose of this function is to turn the LED off.
Could you explain why two commands are needed for this?

You don't need fled_bit, just assign the result to led->current_iout.

Could you shortly describe the function of above three registers?

Please align two above lines to the opening parenthesis.

flash_brightness_offset variable is redundant.

flash_tm_offset variable is redundant.

Does the device allow for setting flash brightness separately for
each iout? Currently it looks like the setting is shared.

Same here - there is no need for flash_tm_offset and
flash_brightness_offset variables.
