Summary
usb: typec: displayport: Fix potential deadlock
Details

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

usb: typec: displayport: Fix potential deadlock

The deadlock can occur due to a recursive lock acquisition of cros_typec_altmode_data::mutex. The call chain is as follows: 1. crostypecaltmodework() acquires the mutex 2. typecaltmodevdm() -> dpaltmodevdm() -> 3. typecaltmodeexit() -> crostypecaltmodeexit() 4. crostypecaltmode_exit() attempts to acquire the mutex again

To prevent this, defer the typec_altmode_exit() call by scheduling it rather than calling it directly from within the mutex-protected context.
