Detail

In the Linux kernel, the following vulnerability has been resolved:

extcon: Modify extcon device to be created after driver data is set

Currently, someone can invoke the sysfs such as state_show() intermittently before dev_set_drvdata() is done. And it can be a cause of kernel Oops because of edev is Null at that time. So modified the driver registration to after setting drviver data.

- Oops's backtrace.

Backtrace: [] (state_show) from [] (dev_attr_show) [] (dev_attr_show) from [] (sysfs_kf_seq_show) [] (sysfs_kf_seq_show) from [] (kernfs_seq_show) [] (kernfs_seq_show) from [] (seq_read) [] (seq_read) from [] (kernfs_fop_read) [] (kernfs_fop_read) from [] (__vfs_read) [] (__vfs_read) from [] (vfs_read) [] (vfs_read) from [] (ksys_read) [] (ksys_read) from [] (sys_read) [] (sys_read) from [] (__sys_trace_return)
