Subject: [PATCH] clk: sunxi-ng: multiplier: Fix fractional mode
|
|
|
|
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")
