Subject: [PATCH V2 06/20] i3c: mipi-i3c-hci: Switch PIO data allocation to devm_kzalloc()
Date: Thu,  8 Jan 2026 10:05:44 +0200	[thread overview]
Message-ID: <20260108080558.21767-7-adrian.hunter@intel.com> (raw)
In-Reply-To: <20260108080558.21767-1-adrian.hunter@intel.com>

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