Subject: drm: rcar-du: Use 1000 to avoid misunderstanding in rcar_du_dpll_divider()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b45c138502ad8dc84f50694430da293678c6d9cc;p=linux.git

drm: rcar-du: Use 1000 to avoid misunderstanding in rcar_du_dpll_divider()

It is difficult to understand its scale if number has many 0s.
This patch uses "* 1000" to avoid it in rcar_du_dpll_divider().
