Message-ID	<20260203-reset_worker_deadlock-v1-0-7ed889b5bf19@oss.qualcomm.com>

This series fixes a deadlock in mhi_ep_reset_worker() where state_lock is
acquired twice, and adds missing lock protection for mhi_state accesses
in mhi_ep_handle_syserr() and mhi_ep_power_up() to prevent race conditions
and state machine corruption.
