Message-Id: <20240821064958.4059221-1-yujiaoliang@vivo.com> Date: Wed, 21 Aug 2024 14:49:58 +0800 From: Yu Jiaoliang <yujiaoliang@...o.com> To: Linus Walleij <linus.walleij@...aro.org>, linux-arm-kernel@...ts.infradead.org, linux-gpio@...r.kernel.org, linux-kernel@...r.kernel.org Cc: opensource.kernel@...o.com Subject: [PATCH v1] pinctrl: nomadik: Use kmemdup_array instead of kmemdup for multiple allocation Let the kememdup_array() take care about multiplication and possible overflows.
