Subject: [PATCH 06/17] i3c: mipi-i3c-hci: Switch PIO data allocation to devm_kzalloc()
Date: Fri, 19 Dec 2025 16:45:23 +0200	[thread overview]
Message-ID: <20251219144534.84391-7-adrian.hunter@intel.com> (raw)
In-Reply-To: <20251219144534.84391-1-adrian.hunter@intel.com>

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