Subject: [PATCH 03/18] dbtr: Fix endian conversion in trigger install handler
Date: Fri, 13 Mar 2026 15:19:32 +1000 [thread overview]
Message-ID: <20260313051948.4017134-4-npiggin@gmail.com> (raw)
In-Reply-To: <20260313051948.4017134-1-npiggin@gmail.com>
An endian conversion was missed loading tdata1 from shm. Add the
conversion and change the variable name from ctrl to tdata1 while here.
