From 4bfba7b360da70ed209969848bbe6e750254a759 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 8 Jun 2026 08:43:11 +0300 Subject: i3c: master: Export i3c_master_enec_disec_locked() The existing i3c_master_enec_locked() wrapper always treats a NACKed ENEC CCC as a failure (M2 error). However, broadcasting ENEC to enable Hot-Join is legitimately useful even when no I3C devices are currently present on the bus, in which case the broadcast will be NACKed and should not be reported as an error. The underlying helper i3c_master_enec_disec_locked() already accepts a suppress_m2 flag that lets callers ignore such NACKs. Expose it so that a subsequent patch enabling Hot-Join events can issue ENEC with M2 suppression.
