From f91f9ece67972885fd41d06dfd034dcce057ef20 Mon Sep 17 00:00:00 2001 From: Erick Archer Date: Sun, 2 Jun 2024 19:23:54 +0200 Subject: [PATCH] iio: event: use sizeof(*pointer) instead of sizeof(type) It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). At the same time refactor the NULL comparison. This patch has no effect on runtime behavior.
