Don't blindly copy/paste comments from other drivers. There is no driver for the devices you are mentionning so the end of the comment is confusing. The 3 first lines were enough

From your comment, I understand that some child are critical, not this particular (or at least, not directly). So this can be removed AFAICT You should even need CLK_IGNORE_UNUSED for this one since the clock will already be enabled before the late_init() kicks in
