5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuan Can <yuancan@xxxxxxxxxx>
[ Upstream commit 32b0901e141f6d4cf49d820b53eb09b88b1f72f7 ]
When platform_device_register_full() returns error, the gsmi_init() returns
without unregister gsmi_driver_info, fix by add missing
platform_driver_unregister() when platform_device_register_full() failed.
Fixes: 8942b2d5094b ("gsmi: Add GSMI commands to log S0ix info")
