Subject: [PATCH v2 3/8] Bluetooth: use inclusive language to describe CPB
From: Archie Pusaka <apusaka@...omium.org>
This patch replaces some non-inclusive terms based on the appropriate
language mapping table compiled by the Bluetooth SIG:
https://specificationrefs.bluetooth.com/language-mapping/Appropriate_Language_Mapping_Table.pdf
Specifically, these terms are replaced when describing the
connectionless peripheral broadcast feature:
master -> central
slave -> peripheral
