Subject: [PATCH] phy: qcom: use struct_size instead of sizeof
Date: Thu,  9 Dec 2021 11:21:14 +0800	[thread overview]
Message-ID: <20211209032114.9416-1-guozhengkui@vivo.com> (raw)
In-Reply-To: <20211207131642.5313-1-guozhengkui@vivo.com>

Use struct_size() to get the accurate size of `clk_hw_onecell_data`
with a variable size array, instead of sizeof(data) to get the size
of a pointer.
