Subject: [PATCH v4 2/4] clk: mediatek: Provide mtk_devm_alloc_clk_data
Date: Mon, 22 Aug 2022 17:26:50 +0200 [thread overview]
Message-ID: <20220822152652.3499972-3-msp@baylibre.com> (raw)
In-Reply-To: <20220822152652.3499972-1-msp@baylibre.com>
Provide a helper that replaces the kzalloc with devm_kzalloc so error
handling gets easier.
