[PATCH 4.14 70/78] drm/radeon: fix fb_div check in ni_init_smc_spll_table()

[Sasha Levin]

From: Denis Efremov <efremov@xxxxxxxxx>

commit 35f760b44b1b9cb16a306bdcc7220fbbf78c4789 upstream.

clk_s is checked twice in a row in ni_init_smc_spll_table().
fb_div should be checked instead.

Fixes: 69e0b57a91ad ("drm/radeon/kms: add dpm support for cayman (v5)")
