Subject: [PATCH] mips: lantiq: add support for clk_get_parent()
Date:   Sun, 14 Nov 2021 17:20:51 -0800
Message-Id: <20211115012051.16302-1-rdunlap@infradead.org>
MIME-Version: 1.0

Precedence: bulk

Provide a simple implementation of clk_get_parent() in the
lantiq subarch so that callers of it will build without errors.

Fixes this build error:
ERROR: modpost: "clk_get_parent" [drivers/iio/adc/ingenic-adc.ko] undefined!

Fixes: 171bb2f19ed6 ("MIPS: Lantiq: Add initial support for Lantiq SoCs")
