The enum ufs_hid_state values are contiguous and start from 0, maybe change switch-state to :

#define NUM_UFS_HID_STATES 6
static const char *ufs_hid_states[NUM_UFS_HID_STATES] = {
    "idle",
    "analysis_in_progress",
    "defrag_required",
    "defrag_in_progress",
    "defrag_completed",
    "defrag_not_required"
};

static const char *ufs_hid_state_to_string(enum ufs_hid_state state) {
    if ((unsigned int)state < NUM_UFS_HID_STATES)
        return ufs_hid_states[state];
    return "unknown";
}
