Subject: [PATCH 2/3] i2c: busses: nomadik: Use devm_clk_get_enabled()
Date: Sun, 11 Jun 2023 03:37:00 +0200	[thread overview]
Message-ID: <20230611013701.1464025-3-andi.shyti@kernel.org> (raw)
In-Reply-To: <20230611013701.1464025-1-andi.shyti@kernel.org>

Replace the pair of functions, devm_clk_get() and
clk_prepare_enable(), with a single function
devm_clk_get_enabled().
