[PATCH v2 0/2] bus: mhi: ep: Fix state_lock protection issues

[Sumit Kumar]

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

Changes in v2:
- Move `mhi_ep_mmio_reset()` out of state mutex lock.(Mani).
- Removed the mutex lock from `mhi_ep_handle_syserr()`, since the caller of
  mhi_ep_handle_syserr() holds the lock.(Mani)
- Link to v1: https://lore.kernel.org/r/20260203-reset_worker_deadlock-v1-0-7ed889b5bf19@xxxxxxxxxxxxxxxx
