From 56f8c1759be90f139056a61328ffbf168cef895f Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Fri, 6 Dec 2024 23:07:23 +0100 Subject: [PATCH] =?utf8?q?iio:=20proximity:=20aw96103:=20Constify=20struct?= =?utf8?q?=20iio=5Finfo=E2=80=8B?= MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 'struct iio_info' is not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers.
