From 16aed0a6520ba01b7d22c32e193fc1ec674f92d4 Mon Sep 17 00:00:00 2001 From: Frank Li Date: Mon, 21 Oct 2024 11:45:06 -0400 Subject: i3c: master: Replace hard code 2 with macro I3C_ADDR_SLOT_STATUS_BITS Replace the hardcoded value 2, which indicates 2 bits for I3C address status, with the predefined macro I3C_ADDR_SLOT_STATUS_BITS. Improve maintainability and extensibility of the code.
