Subject: [PATCH v4 1/5] mailbox: zynqmp: fix counts of child nodes
Date: Tue, 28 Feb 2023 13:02:12 -0800 [thread overview]
Message-ID: <20230228210216.447373-2-tanmay.shah@amd.com> (raw)
In-Reply-To: <20230228210216.447373-1-tanmay.shah@amd.com>
If child mailbox node status is disabled it causes
crash in interrupt handler. Fix this by assigning
only available child node during driver probe.
