From adf91d9e1983dec3d5fabc273e8ff89918b852c1 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andr=C3=A9=20Draszik?= Date: Wed, 9 Apr 2025 21:37:39 +0100 Subject: [PATCH] mfd: sec: Change device_type to int MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Now that sec-i2c doesn't match device type by pointer casting anymore, we can switch the device type from unsigned long to int easily. This saves a few bytes in struct sec_pmic_dev due to member alignment.
