Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/chrome: cros_usbpd_notify: Fix error handling in cros_usbpd_notify_init()
The following WARNING message was given when rmmod cros_usbpd_notify:
Unexpected driver unregister!
WARNING: CPU: 0 PID: 253 at drivers/base/driver.c:270 driver_unregister+0x8a/0xb0
Modules linked in: cros_usbpd_notify(-)
CPU: 0 PID: 253 Comm: rmmod Not tainted 6.1.0-rc3 #24

RIP: 0033:0x7f333fe9b1b7
The reason is that the cros_usbpd_notify_init() does not check the return
value of platform_driver_register(), and the cros_usbpd_notify can
install successfully even if platform_driver_register() failed.
Fix by checking the return value of platform_driver_register() and
unregister cros_usbpd_notify_plat_driver when it failed.
