Subject: [PATCH] clk: rockchip: Fix error pointer check after rockchip_clk_register_gate_link()
Date: Tue,  5 Aug 2025 07:03:58 +0400	[thread overview]
Message-ID: <20250805030358.3665878-1-linmq006@gmail.com> (raw)

Replace NULL check with IS_ERR_OR_NULL() check after calling
rockchip_clk_register_gate_link() since this function
returns error pointers (ERR_PTR).

Fixes: c62fa612cfa6 ("clk: rockchip: implement linked gate clock support")
