Subject: [PATCH 1/7] clk: samsung: s3c64xx: Declare s3c64xx_clk_init() in shared header
Date: Wed, 29 Jul 2020 18:09:36 +0200
Message-ID: <20200729160942.28867-2-krzk@kernel.org> (raw)
In-Reply-To: <20200729160942.28867-1-krzk@kernel.org>

The s3c64xx_clk_init() is defined and used by clk-s3c64xx driver and
also used in mach-s3c64xx machine code.  Move the declaration to a
header to fix W=1 build warning:

    drivers/clk/samsung/clk-s3c64xx.c:391:13: warning: no previous prototype for 's3c64xx_clk_init' [-Wmissing-prototypes]
      391 | void __init s3c64xx_clk_init(struct device_node *np, unsigned long xtal_f,
