[PATCH 6.2 517/663] clk: at91: clk-sam9x60-pll: fix return value check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Claudiu Beznea <claudiu.beznea@xxxxxxxxxxxxx>

[ Upstream commit 1bd8e27fd0db0fe7f489213836dcbab92934f8fa ]

sam9x60_frac_pll_compute_mul_frac() can't return zero. Remove the check
against zero to reflect this.

Fixes: 43b1bb4a9b3e ("clk: at91: clk-sam9x60-pll: re-factor to support plls with multiple outputs")
