Subject: [PATCH 01/19] clk: at91: clk-generated: continue if __clk_determine_rate() returns error
Date: Wed, 15 Jul 2020 14:24:09 +0300 [thread overview]
Message-ID: <1594812267-6697-2-git-send-email-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <1594812267-6697-1-git-send-email-claudiu.beznea@microchip.com>
__clk_determine_rate() may return error. Skip the current step
in case of error.
Fixes: 1a1a36d72e3d3 ("clk: at91: clk-generated: make gclk determine audio_pll rate")
