From 973dd9c4db4746200f88fe46e30eada7054fdbea Mon Sep 17 00:00:00 2001 From: Erick Archer Date: Fri, 24 May 2024 19:11:51 +0200 Subject: [PATCH] Bluetooth: 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). This patch has no effect on runtime behavior.
