Tom Rix fa31311c31 leds: mt6323: move period calculation
clang static analysis reports this problem

leds-mt6323.c:275:12: warning: Division by zero
        duty_hw = MT6323_CAL_HW_DUTY(*delay_on, period);
                  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This is because period can be 0.

	period = *delay_on + *delay_off;

There is a later check that *delay_on/off are valid.

	if (!*delay_on && !*delay_off) {
		*delay_on = 500;
		*delay_off = 500;
	}

Setting the delay_on/off means period needs to be recalculated
anyway.  So move the period statements after this check.

Fixes: 216ec6cc4c19 ("leds: Add LED support for MT6323 PMIC")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
