Subject: [PATCH] gpio: Convert to subsys_platform_driver()
Date: Wed, 4 Nov 2026 19:33:09 +0800 [thread overview]
Message-ID: <20261104113309.1634121-1-peng.fan@oss.nxp.com> (raw)
From: Peng Fan <peng.fan@nxp.com>
Replace the open-coded subsys_initcall()/module_exit() platform driver
registration with subsys_platform_driver().
No functional change.
Signed-off-by: Peng Fan <peng.fan@nxp.com>
