Subject: [PATCH 4.14 14/14] clk: at91: generated: set audio_pll_allowed in at91_clk_register_generated()
Date: Mon, 2 Dec 2019 10:03:12 +0000 [thread overview]
Message-ID: <20191202100312.1397-14-lee.jones@linaro.org> (raw)
In-Reply-To: <20191202100312.1397-1-lee.jones@linaro.org>
From: Alexandre Belloni <alexandre.belloni@bootlin.com>
[ Upstream commit c1e4580a1d0ff510d56268c1fc7fcfeec366fe70 ]
Set gck->audio_pll_allowed in at91_clk_register_generated. This makes it
easier to do it from code that is not parsing device tree.
Also, this fixes an issue where the resulting clk_hw can be dereferenced
before being tested for error.
Fixes: 1a1a36d72e3d ("clk: at91: clk-generated: make gclk determine audio_pll rate")
