This patch series addresses two critical issues in the Huawei Matebook E Go
UCSI driver that were preventing proper functionality and causing potential
use-after-free scenarios.

The first patch fixes a probe failure by adding the missing poll_cci to the
UCSI operations structure, which is required by the UCSI core for proper
initialization.

The second patch resolves use-after-free vulnerabilities where a delayed
work item could access freed memory after device or module removal, by
ensuring proper cancellation of the work item in gaokun_ucsi_remove().
