Subject: [PATCH V3 06/21] i3c: mipi-i3c-hci: Switch PIO data allocation to devm_kzalloc()
Date: Tue, 13 Jan 2026 09:26:47 +0200	[thread overview]
Message-ID: <20260113072702.16268-7-adrian.hunter@intel.com> (raw)
In-Reply-To: <20260113072702.16268-1-adrian.hunter@intel.com>

The driver already uses managed resources, so convert the PIO data
structure allocation to devm_zalloc().  Remove the manual kfree().
