Subject: [PATCH 6.12.y 1/3] i3c: master: Replace WARN_ON() with dev_err() in i3c_dev_free_ibi_locked()
Date: Wed, 9 Sep 2026 20:17:54 -0400 [thread overview]
Message-ID: <20260910001756.3748845-1-sashal@kernel.org> (raw)
In-Reply-To: <2026090419-hunchback-antics-d9e3@gregkh>
From: Adrian Hunter <adrian.hunter@intel.com>
[ Upstream commit 471895799c2f46688792e175ced936ffeb6cdf01 ]
IBI disable failures are not indicative of a software bug, so using
WARN_ON() is not appropriate. Replace these warnings with dev_err().
