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

The reason is that the crosusbpdnotifyinit() does not check the return value of platformdriverregister(), and the crosusbpdnotify can install successfully even if platformdriver_register() failed.
Fix by checking the return value of platformdriverregister() and unregister crosusbpdnotifyplatdriver when it failed.
