Subject: [PATCH] clk: sunxi-ng: multiplier: Fix fractional mode
Git-commit: 1e92ae651e766603d9c582ff356abf96ae90d933
Patch-mainline: v4.14-rc1
References: bsc#1051510
Driver for multiplier clock is missing a call to
ccu_frac_helper_enable() when fractional mode is selected.
Add a call to ccu_frac_helper_enable().
Fixes: d77e8135b340 ("clk: sunxi-ng: multiplier: Add fractional support")
